If you are looking for a unique stay this place is excellent! The decor is fun and the hallways are reminiscent of strolling through an art gallery. We loved having breakfast (which was included) in the stylish and light filled salon every morning. As a vegan/vegetarian couple we usually avoid hotel breakfasts but we were pleasantly surprised to find plenty of options for us. With all the different styled rooms, we ended up with a pretty basic looking blue room but the bathroom was bright and fun, bed was comfy. We walked through a Claret red Baroque Decor hallway on the way to our room, we would love to stay in one of those rooms if we have the opportunity to return.

Not a big deal but there wasn't a Metro stop super close. Vienna's transportation system seems somewhat complicated and we only had a couple days so might have missed a nearby bus or tram line that would have worked too. Either way, the hotel is in a cool neighborhood with restaurants and Museums nearby but we walked a lot (which was fine, we were getting our steps in!). It looks like they might be adding a new line around there...

Breakfast is outstanding, varied and delicious. It is better to avoid 9-10 am when it gets extremely crowded and difficult to find a table. The first day, we ended up with a small table for 3. This was fixed by coming at 8 am the next day. The location is excellent.

In some sense, Altstadt falls short of being a real hotel. You are often left on your own. We travel with a wheelchair, a pet and quite a bit of luggage and we were not offered any help unloading the car and/or getting to our room. We had to fetch the luggage cart, take everything up ourselves through doors that are not really accessible. Similarly, while very pleasant, the terrace was definitely not the "relaxing oasis" advertised: the beer was tepid and the terrace populated by entitled couples with loud, free-roaming kids.

Everything including wonder staff in every department

Nothing

The breakfast was very good with ecological and regional products; the bread was fresh and tasty. The tea time with cake was also nice. The Saskia Suite had plenty of space for 3 person and was nicely decorated. The whole hotel has a casual/modern art gallery character. The beds were very comfortable and it was a nice detail to find always fresh apples in our coffee table. I got a nice card and a chocolate from the staff on my birthday. The Salon is also quite cozy, specially in the evening when you can sit to read and have a cocktail listening to soft jazz music. Distance to the museum quartier was excellent!

The walls to the suite next door where a bit too thin; we could hear our neighbours until late during the night or the elevator going up and down, also noise from the street (ambulances, police cars, church bells, ...) was audible. The water in the shower took an eternity to get warm and then got luke warm. It was not possible to connect mobile devices to the tv screen (USB and Bluetooth where disabled) and the reception said it simply was not possible to connect devices to the screen. This was a big dissapointment specially for our teenager.

This hotel has a character itself. A very pleasant scent welcomes you when the hotel door's opened. The artworks and style of decorations at the lobby and BF room make me feel lively. Breakfast is something special, both the taste and the looks. Staff are very helpful and nice.

Each room has its own style. The room's decor I stayed a bit quirky, which is not match my preference. So better ask for the style of the room you like before check-in. There's something not functional in our room, such as the outlets under the night tables, every time you have to use it you have to drag the table off the wall or kneel down on the floor. We have TV and Marshall speaker in our room, but we cannot turn-on both.

The property is in a great location and the staff are very welcoming. The rooms are clean and well designed. The dining areas are comfortable and stylish. There is a huge variety of food and drink available for breakfast and we loved the afternoon tea and cake. The staff work hard to make you feel welcome during your stay and would definitely return to this hotel.

The staff is amazing. They make you feel welcome and ensure all is well from the second you enter the building throught your entire stay. So many nice touches here and there that make this a great place. I warmly recommend this hotel and would definitely stay again.

I know shower caps could be requested at the reception, but when you only realise that after undressing, calling the reception is out of question. It is more convenient when these things are readily available in the room.

Beautiful fin-de-siecle building, many original art objects, the breakfast salon, the breakfast staff. Breakfast was ok, not so many options but high-quality products.

The reception staff where not really engaging and we always had the impression we were bothering them. No question how our journey were, and also no offering for a tea, water or prosecco, although everything was placed near the reception. But we‘ve got a small upgrade.

The location is wonderful. We walked to 4 Christmas markets easily. The breakfast in the morning was delicious and the staff was lovely.

The only negative was that our room was on the dark side. There was an incredible chandelier and the room was elegant. But when I look at the pictures online of the other rooms they are bright and cheery. I just always prefer a lot of light and maybe we got the only room that didn’t have that.

Beautiful breakfast room, where you could also get cake and drinks in the afternoon. Lovely breakfast staff as well, was an absolute pleasure starting the day this way:) the spinach and feta quiche on their afternoon/room service menu is truly delicious. Perfect location, great area with lots of nice restaurants, cafes, smaller/vintage/artistic shops.

No wardrobe in room, just a rail with hangers but no shelves for underwear, t-shirts, etc. No shelves in bathroom either. Daily between roughly 8-9:30am extreme slamming of doors, makes room shake (1st floor rooms).
