Staying at João's place was nice. The apartment is designed with a personal-vintage touch and you could see that a lot of thought was put in to the design. João is a great host, he was waiting for us at the apartment on the check in time and explained everything.
The place is spacious and clean, but shares a thin wall with the neighboring apartment - which caused some noise during the stay. Also- the hot water boiler is shared so it is turning on with a loud noise whenever someone is turning on the water.
The street of the apartment is very active and loud during the night so it's not possible to keep the window open when sleeping (Although it's ok when you close all windows and turning the A/C on).
If you are looking to stay in Bairo Alto and being close to the night life, we recommend João's place.
