Room was lovely, bed was comfortable, bathroom was beautiful, breakfast was delicious and the staff were amazing. It was a little bit of a walk into Old Town but Uber was inexpensive. Would definitely stay there again.

Very nice hotel
108mm House is a very nice apartment hotel. Our room has a beautiful view overlooking the Douro river. The hotel room is nicely furnished with well equipped kitchen facilities including oven, microwave oven, cooker, coffee machine, fridge and freezer. The room is spotlessly clean.
Bruno, the hotel manager, is very friendly, helpful and informative. He gave us a lot of useful information about Porto, including nice restaurants and transportation information.
The breakfast served by the cafe is very tasty. We had a very good experience staying in 108mm House.

We had a wonderful stay here. It was perfect for us. The apartment was comfortable. We traveled with family and had two apartments. We loved hanging out by the pool after the day sightseeing. We had breakfast included which was definitely worth it! Our room had a beautiful view of the river. We enjoyed walking around the area. The staff at the hotel were very friendly and accommodating. They went out of their way to make sure we were happy. There is no room cleaning during they stay, which was fine with us but something to n ow. Would definitely stay again!

Bruno, Katarina (sp), Aleshia (sp) and everyone of the staff were amazingly friendly, communicative, flexible and kind. This gem of a hotel, opened in 2022 is hidden in a residential area, along the waterfront near the Electric Car Museum and a grocery store. It is along the "tourist" tram and bus line. Once you enter the foyer, the design, style, furnishing, lighting are so welcoming and bright and modern. The breakfast choices are delicious, well prepared and beautifully plated. The rooms (which vary nicely) are well appointed, sooo smoothly arranged and functional. We took a tour with Bruno of several others with more and less capacity for guests. The small rooftop area with a pool and open sitting areas welcome some privacy and space. We will be back (hopefully with a larger group soon). Saudade

The hotel is extremely well managed. The staff from check in to check out were outstanding. We had issues with charging our phones since we came from North America and didn't have European adapters but Bruno helped sort all that out. Catarina was very helpful with advice on what to do and where to go. The room was very clean. The bathroom was roomy and modern. The hotel is quiet and removed from the hustle and bustle but an easy and affordable Uber ride from popular tourist spots. We particularly enjoyed breakfast here before exploring the city. The food here is good quality and made with great care, attention and detail. The breakfast is as good and if not better than restaurants that specialize in brunch menus. A special thank you to Catarina, Bruno, Sara and the staff in the kitchen. Cheers!

We had a really lovely stay at 108MM. The apartment was stylish, comfortable and spacious - perfect for us and our daughter (aged 6). The kitchenette was brilliantly equipped for the few nights we chose not to dine out somewhere. The views of the river were amazing to wake up to every day and the beds were very comfortable too. Our daughter was very pleased she could get Netflix and Disney on the TV. Bruce is a fantastic host and being able to communicate via whatsapp to arrange transfers and room cleaning in advance was so useful and helpful. We also very much appreciated the list of recommended restaurants, where to get all transport from and local Porto card as well as the lovely glass of port on arrival! And we were allowed to check in early at no extra cost which was hugely appreciated. Its only a short and picturesque walk along the river to the Porto old town, so really near to so many restaurants, museums and sites. And it was very handy having a main bus and tram stop right outside. Really could not recommend this place enough - we had such a great week.
