I like the design of the appartement very much, it was one reason to choose it. It is very special and functional and I think Gianluca designed and built the furniture by himself. Everything which you need is prepared for you. The biggest part of the appartement is clean but in the kitchen and bathroom it could be better.
Its a good location to discover the city. In the most time we walked in the city, sometimes we use the metro at Termini e.g. to visit Vatican. The neighborhood is really lively. But also very suspect. (Someone wanted to sell us drugs before we checked in. ;) But it was ok, nothing bad happens.) There are many young students on the piazza in front of the door, they make a big party every night. I have to say that we came to Rome for sightseeing and not for party, so it was not the best neighborhood for us. It was impossible to sleep one night without waking up.
I would recommend to eat in one restaurant on the way to the supermarket (24/7 - 5 minutes to walk) the "Porca Vacca" its verry good and the price is fair as well.
