Had a very nice stay at Frederico's place. He was fast and friendly with communication and check in was very easy. The apartment is beautiful and modern on the inside, with just about all the amenities you could ask for - including a VERY comfortable bed. In a very good location just a short walk from the Trevi fountain, Pantheon, Borghese Gardens, and several other attractions, as well as the metro station. Would highly recommend a stay here for solo travelers or couples.
