I had a great time staying at Rene's appartment. He is a very good host, since from the first moment he was very attentious and explained all the facilities of the appartment and of the city. The appartment is really well located in an old style building (with elevator), near a metro station (less than 5 minutes walk), a very good restaurant (Vechia Roma - just on the corner) a very good place to have breakfast (Kristal something if I am not mistaken - it is in front of the metro station nearby) and near to Coliseum (about 10 to 15 minutes walk), near to the big station of Rome, where the trains from other cities arrive. (about 10 to 15 minutes walk) I would stay there again, alone, with my girlfriend, friends or family, and I strongly recommend it, I am sure you won't regret it.
