We had a very pleasent stay of 10 days in this Apartment.
The host waited for us to welcome us even if we had a lot of delay with our flight. And he was extremely welcoming! We found the apartment warm, very clean and there was something to eat and to drink (as it was rainy, cold and late on sunday evening it was even more appreciated from us).
The apartment ist very well euipped and very comfortable, there is really everything you need. It is very good situated and actually you can visit almost everything by foot if you like (which is the best thing to do in Rome). The street is calm, you do not hear any noises if you are in the apartment, but there are may restaurants, cafes, ice-cream-cafes and supermarket just a couple of minutes by foot.
The apartment is also family friendly if you plan to take your Kids (we had a 8 months old baby).
We really suggest to enjoy Rome staying at Antonios place.
