Frank was really a great host. The check in worked great and although we arrived before the official check in time we could leave our luggage in the room. The tips and restaurant recommendations are really great. The flat is very modern and clean and very quiet. The location of the flat is really perfect, the Colosseum is about 15 minutes away and the Vatican can be reached by metro in about 20 minutes. It is a really great flat with a great location and we can definitely recommend it :)
