The apartment is exactly as described and nothing hidden in the pictures. What you see is what you get and more. The bed is comfortable and the room large enough for two people. Everything was in perfect working order and you surely get more than what you pay for. Air-conditioning in 2 rooms is definitely a nice bonus! Just so you know, there is no iron, so bring your travel iron with if you need one!
The area is very nice and I'd say the metro is actually about 3 blocks away (a bit further than what it says) but a comfortable walk. No complaints at all.

Andrea was very easy to reach and his English is better than he thinks. He is a very accommodating and friendly host, gave some good tips on where to go and I will definitely stay at his place again if I come to Rome.
