I don't think there is a better place to stay in Rome. This apartment is simply perfect! Really well located (less than 10 min walkint to Termini train Station and 5 to Colisseo); clean, warm and good decorated. It is quite small but more enough for a couple.
Lorenzo was waiting for us with a big smile despite arriving really late and we could do the check out in the afternoon because he didn't have other guests coming :)
Just to recap: great place and great host, will definetely come again!
