We enjoyed staying in Paulo's studio. It is nothing super special, but everything works fine. The bed and the shower are amazing.
The location is very well connected to the rest of the city with a metro station at 50m distance. There are also a few great restaurants and bars around. The neighbourhood does become a bit sketchy after dark.
We were sleeping on the the ground floor and it was quite noisy. My girlfriend could not sleep properly. Something to take into account.
