Having a Private Pool/Spa is very nice and you can also book a fantastic massage treatment in the room next to it. The hotel and all the rooms are gorgeous as well and very unique. If you want to stay in a fancy hotel in Paris, you have a lot of options on the table, but Maison Proust is easily the most unique.

You can only book the Private Spa/Pool for one hour per day - I highly suggest you book in advance as well.

Fantastic Location. Very beautiful decoration with unique fabrics and wall papers all over the place. the staff was super polite and helpful. the Spa facilities were fantastic considering this is a boutique city hotel. It was nice that there was always a discreet jazz music at the back in communal areas making our stay more relaxing. the bar offers well crafted cocktails.

Although the room we stayed was very beautifully decorated, the size could have been a bid bigger to accommodate the luggage and stuff of two adults.

Good location, right next to the Marais but in a more relaxed and quiet neighbourhood, walking distance from centre Pompidou, Louvre, Notre Dame,... The hotel is brand new. You should have a look at the pictures to see if the hotel style suits your taste, it is definitely not a minimalistic interior... The staff was extremely friendly and went above and beyond to offer the best experience. Breakfast was very nice. The room is of course small (Paris...) but with quality materials. The major surprise was the pool/hamam area, which you can reserve for private use for an hour (definitely a recommendation, although I wouldn't have thought so in the center of Paris).

High price category, but honestly this is to be expected for the combination of location and the level of service and quality. The rooms are all 'Paris-size', so going for a standard room doesn't make you loose out on a lot of extra space and makes it a bit more affordable.

Stylish. Great art and deco. Small yet very Comfortable and well equipped beautifully designed unique rooms. Atmosphere. Location. Staff friendliness.

The breakfast Danish pastries should be better.

If there were a seven star rating on Booking.com, I would give Maison Proust Hotel & Spa La Mer seven stars! This is truly one of the most beautiful hotels I have ever stayed in, and the staff were so friendly and courteous! The interior design, by Jacques Garcia, is exquisite, with beautiful, original art chosen by the owners. But what puts this hotel over the top is the private pool and steam room. Each guest may book the pool for one hour a day to themselves in this beautiful, Moroccan-themed spa! When I arrived, I was stressed-out and over-worked; one hour at this pool and my stress melted away. Though the rooms are small, they are beautifully designed, quiet, and so nicely arranged. The bed was so comfortable and the staff delivered our breakfast in bed each morning on request. The room service menu does not disappoint, and the cocktails are so delicious in the beautiful bar. I have stayed at the Ritz, Paris and some of the best hotels all over the world. I would rate Maison Proust Hotel & Spa La Mer one of the very best. I have found my favorite hotel, and it will be my top choice whenever I am in Paris!

Nothing, it was perfect!

This property embodies everything you dream about when you think of Paris - luxury, beauty, attentiveness, romance! The hotel has all the details and more you’d expect from a 5-star boutique property, while also feeling bespoke (like you’re lucky to have found it). The staff were fabulous from the moment we arrived, and personalized the experience and service to us and our liking - the attentiveness was unparalleled. The hotel is tucked away from the busy street and noise, making it a perfect destination after touristy activities or when we wanted to simply relax. The staff are able to call or schedule cabs that arrive quickly, almost always luxury rides at regular cab prices. It is one of the best hotels we have ever stayed at around the world and we will most certainly go back!

The staff was incredibly kind. They went above and beyond to take care if all of our needs. The hammam after a long day of shopping museums and walking around the city is a must!! The owner was there everyday always making sure we enjoyed our stay and were well taken care of. Its so lovely to stay in a small and chic hotel where you can see that the owner cares so deeply and looks after the smallest but most important details. I have never left a review before but they were so kind and lovely to me and my teenage kids I will stay every time I come to Paris.

Amazing luxury boutique hotel in the heart of the more beautiful part of Marais. Walking distance to great restaurants and shopping. Friendly and caring staff giving us a wonderful stay after both the Paris marathon and our engagement :) The underground private spa is beautiful and as it is only for hotel guests. You book it for an hour of private bath and steam sauna. Will definitely be back as this is truly one of the best hotels we have stayed at. An exclusive experience worth a trip by its own.

EVERYTHING. This is best hotel experience i ever had in Paris. Full stop. The Hotel is niche and has no sign, golden blue signature hues welcome you and makes you feel at home. Perhaps a fancy home. Staff is exceptional. Atmosphere top notch. Food and beverage above expectations. the suite I stayed in had the most amazing facilities and the Spa is outwardly. You can walk anywhere, amazing shop and restaurants as well as a small market nearby. All is all five stars experience, Cannot wait to go back,

The interior design. Particularly the spa and the bar. It was probably one of the best massages I have ever had and the space was extremely comfortable.

Our shower leaked and the water went everywhere due to the style of shower head.
