First things first, Ernesto is a really nice guy and his project, bringing young people together and having a good time, is supportable. If you want to live in an artistic and hip district with a lot of restaurants and bars Trastevere is the place to be. The apartement is big with a fully equiped kitchen and livingroom.
Now back to business. The room had everything we needed but it is not a room in which you want to stay longer than 3 nights. The bathrooms seem like they get cleaned twice a week.
However The communication was perfect and we really enjoyed our stay in Rome.
