Valentina and Alessandro are about as good as hosts get. The rooms are clean and comfortable, and the location is fantastic - in the heart of Rome, in what used to be a monastery, so it's quiet and peaceful, which is rare for such a noisy city.
Vale and Ale are attentive to your needs and always helpful, but will also respect your privacy if you wish. If you are lucky you might also get a visit in the garden from Miro, the resident cat.
If you are planning a trip to Rome do yourself a favour and stay at Greenhouse Colosseo. You will not be disappointed!
