This is an excellent apartment. It's clean, modern and nicely located. San Lorenzo is quite a cool area with some superb restaurants. One can walk to the centre of Rome (e.g. Fontani di Trevi) in about 45 mins, although of course there are lots of quicker public transport options. (I like walking :)

Amedeo met me at the apartment and was very helpful and friendly. I wouldn't hesitate to recommend staying here. The downstairs can serve as a studio-apartment-style sleeping area (with a double bed) adjoining the kitchen, while upstairs there is a lovely double bedroom.

The wifi sucked quite a bit. However, Europe-wide data roaming is only a few quid a day nowadays, so this is unlikely to be an issue unless you plan to spend a lot of time in the apartment. And when in Rome, why would you? ;)
