We recently stayed 2 nights at the Green House Colosseo and absolutely loved it. The location is great - walking distance from Colosseum/Trevi Fountain/Pantheon and well connected through metro/bus routes to other attractions in Rome (less than half hour by metro to the Vatican). The house itself is very clean and comfortable and set in peaceful gated community, with a little garden with the lemon tree (as in the pictures). Valentina and Alessandro are very helpful and accommodating hosts. They offer a dinner service (served in the garden) which we tried and were quite happy with (try the Carbonara, its great!). We needed accommodation for our third and last day in Rome and the Green House was booked. The hosts went out of their way to arrange an alternate accommodation for us nearby and also helped transfer our bags. We have stayed in a few AirBnB places now and the Green House Colosseo has by far set the standard for an excellent and memorable experience.
