My fiance and I booked this hotel for 8 days in Porto. We booked one of the rooms with a hot tub and balcony, and we did not regret that decision at all.
About the room: The room was spacious, airconditioned, clean and nicely decorated - the toilet and shower were seperated in the end of the room where the closet, sink and mirror were, there was a desk/work station, and the bed was big and spacious with a big TV in front that had ChromeCast as well.
The hotel: Staff was friendly, the roomservice/food was actually really tasty (we ordered a grilled steak one night and were very pleased), the breakfast buffet had a great selection of food and ingredients for a mimosa ;-) The indoor pool wasn't huge, but there were not a lot of people, so no problem. There's also showers/changing rooms and a sauna. We did not use the fitness room, but it looked nice.
The location: Perfect - 3 minute walk to Bolhao Market where you can get an icecold glass of wine to sip from, while exploring the many food stalls with tasty tapas. We also went to the Bacalhau restaurant within the market (1st floor) and it was absolutely amazing! In general, you can walk to everything you want to see in Porto from the hotel.
