We loved our stay here. The flat is cosy, quirky and cool - just a stone's throw from the Colosseum and the Forum and a manageable walk even for my ageing mother to the lovely restaurants in Monti. Celio itself has some nice spots too - the park, the churches, some great food and yoga. Massimo and Alessandra are thoughtful, generous hosts who provide everything you need for a welcoming and comfortable stay - down to coffee, cookies and cooking ingredients. There were two of us and we had plenty of space though I think up to four would still work fine. I wouldn't hesitate to book again for my third trip to Rome.
