First of all, Maria was excellent as a host! We had a problem with our reservation at a hotel and she answered as directly! She prepared the studio for us in a few hours and everything was perfect! The room is spacious and clean. It is 2 min by walk from Piazza Navona -so it is mear to everything by walking, it is near bus station to diffrent destinations.
The only problem is the humidity that is a general problem in that area, but Maria told us to leave the air condition open all day - and that worked for us.
I would totally suggest that studio.
