The flat is just as shown in the pictures. Small but comfortable enough for a couple. It has everything we needed, its nice, clean and neat, and It is located in a very nice neighborhood. Also, there's a great market just across the street. Another positive thing, it is located within a walking distance from Roma Termini.
We actually never met Federico and Elena, since they were on vacations on their own, but they were really nice to talk to when making the arrangements.
They also left a welcoming letter in our language (Spanish) with tips and commendations on how to walk around Rome, which was a very nice touch of them, and plenty of food available, for us to have.
We'd loved staying at Casa Edgard, we would totally recommend and we would definitely come back if we ever visit Rome again.
Thank you Federico and Elena, we had an amazing time!
