This flat at the heart of Lisbon is suitable for a single or couple interested in the festive atmosphere of Bairro Alto. If you like to sleep early and need silence at night, this is not the neighborhood for you. I love Lisbon, and this time around I wanted to be in a vibrant environment, so I was mostly ok with the noise. In any case, the post-lockdown re-opening of the bars got people in real festive mode this season, so be prepared.
The flat has all you need for a short summer stay. The communication with the host went smoothly, and she was helpful.
The only reason why I wouldn't recommend this flat is the disgusting sewage smell from the bathroom. At times, with the hot weather, it was almost unbearable, as I could feel the smell in the living room, even with the bathroom door closed. It seems to be something structural about the apartment, as I noticed the bathroom has no ventilation system whatsoever. I have experienced similar problems with other old buildings in Lisbon (therefore I avoid them on longer stays), but this time it was really bad.
I really hope this issue can be fixed, because this is a perfectly functional and central flat.
