The apartment is very nice and spacious, and has two full bathrooms, which is a big plus when there are 4 people.
The location is great, only minutes of walk to the Vatican city. And we walked to the Pantheon, Trevi Fountain, Piazza Venezia, the Colosseum, Roman Forum...
The check-in was easy, Elena was there greeting us and showed us around.
The apartment is on forth-floor, and if you have heavy luggage, it would be a bit work.
Anyway, this is a nice place to stay if you visit Rome.
