- The staff were amazing. I had to arrive later than the check-in time due to issues with train delays and a long trip to get there. They were understanding and waited for me. Very friendly staff who also showed me around and explained how everything in the hotel works. - The design of the hotel (especially the lobby) was very classic and i liked it. - Room had all advertised amenities and everything you might expect like toiletries. Bed was comfy, and the shower was spacious. - Multiple public transportation options around the hotel that take you to points of interest. - Room soundproofing was quite good. Overall, it was very satisfactory, and I would happily stay again if I am around Mannheim.

Great hotel. Wonderful owners, very friendly and helpful. Very spacious bedrooms with comfy beds. Great bathrooms. Very well kept, very clean. Location was great. Lots of easy to access public transport near by if required.

Was not the biggest fan of needing to pay for parking inside. But given the location and the lack of space, friends have told me it's fairly common for hotels in cities.

My stay here for one night was great. The hotel is in a good location in Mannheim near restaurants, the tram, and a park. The room was clean and quiet. The staff here are the real standout. I was greeted on check-in and check-out by very personable people. Would stay here again when passing through Mannheim.

My room had a small a/c unit that had trouble cooling the room. However, it was an unusually hot summer day.

Very friendly staff, very helpful. Very clean room. Good location

AC did not work (was not broken but probably shut down by the hotel) so it was quite warm in the room. Reception is closed at 10pm. No cappuccino or latte for breakfast (just black coffee).

This is a unique privately run hotel, with history. Top clean, new, very quiet. Room is exactly as on the pictures. Location is great too, very quiet but only a 5 minute walk to the city center, 2 minutes to the river, 16 minutes to Hauptbahnhof (Main train station), 2 minutes to a large green park! There is a bakery in the same building, do try their Zitrone roll - it’s amazing!

We felt as if we visited a mansion of a German relative (whom we don't have) The hotel is full of history but also with modern comfort. The room was big, clean, and very pretty. "Wow" was the first word that came out when we entered the room. The gentleman who runs the hotel with his brother was so kind and attentive. We parked our car in a gated garage which used to be a horse stable a century ago.

Nothing

The level of attention to detail in this place was exceptional. Having come directly from a disgusting and dirty Amsterdam hotel, I almost cried with happiness to see the level of cleanliness of my room, and in fact the whole hotel. The show was large and all the equipment was top-spec, easy to use, and consistently excellent.

Nothing. I loved it.

Comfortable room; location is perfect for walking into downtown Mannheim and/or visiting the historic Wasserturm. Front desk was extremely helpful. Parking conveniently available across the street or in front of the hotel. Would recommend for a nice stay in Mannheim.

We loved our room (tower room), it has great lights and a wonderful bathroom with a hot tub and a fancy sink with lights. The room is spacious too. Friendly staff who are happy to help (e.g., call a cab, lend an umbrella) and everything was clean.

I stayed just for one night and I didn't have any particular wishes and even didn't have breakfast at the hotel because I needed to leave for the train station. The stuff at Hotel Mack was very friendly and helpful. The room was super clean, I even mentioned it during check out.

Everything was fine
