Excellent choice, clean, well organized. It looks new and recently renovated. Well located. Definitely, our first choice for the next trip in Lisbon. Owners are friendly and efficient. Check in and check out without the problem. Also, good for reaching by public transport, taxis or cabify/uber.
read other reviews and you can get pretty clear picture of this place: we did not find street to be noisy, also no problem with renovation across the street. Stairs? Well, in Lisbon there are a lot of stairs. But if you don't have problems with mobility, this is not a big issue. Just come and enjoy.
