TL;dr: good place to stay for 2-3 nights, could be better.
The place is very cool and it looks so artistic, with a lot of books and very nice touches all around. We loved that! There are some things that could be better. For example, you'll never meet Marco - we didn't meet him and neither did a lot of people that left reviews, as you'll read them. He just left us the key in a place and instructed us to do the same when we left.
The place is in a good neighbourhood, close to main landmarks on a walkable distance, with lots of good restaurants and bars along the way. But even though it is in a quiet neighbourood, the studio can become very noisy at times, especially early in the morning (cars, scooters, garbage truck) and only sometimes at night, since it is not very well isolated.
We didn't expect the studio to be right at the ground level, with the door opening directly to the sidewalk. Marco told us this just a day before our arrival. It is a safe place though, didn't have any problems.
Marco didn't respond very quickly, but he gave us all the information we needed to know for our stay, afterall, through messages and notes in the studio.
