Andrea and his room-mate are great and friendly hosts, nice to chat with and giving good tips for a pleasant stay. The apartment is cosy and nicely decorated, close to the train line but quiet. I like the "green" orientation with organic food and recycled but stylish furniture. There are several rooms so it's like a small private hostel and you'll also meet other travellers. My room (Monti) was quite small, but perfectly fine for one person with enough storage space... and you're just in there for sleeping anyway ;-) The San Lorenzo neighborhood has a nice atmosphere, not very touristy but with many bars and restaurants frequented by locals. The colosseum/historic centre is easily accessible by public transport or even on foot (approx. 30 min walking distance). Overall, the hospitality and friendliness I experienced made my stay in Rome even better!
