My experience at Marisa's B&B was fantastic! First of all, Marisa and her husband are lovely and deeply nice, they are fond of Rome and it was a pleasure to chat together. They are very flexible with check in/out times and I did appreciate it.
The room is very well equipped, there is everything you can need during you stay. The bar to have breakfast is very close and delicious! The place was perfectly clean. The area is in the heart of Rome, a few meters from the archeologic site of the Roman forum. I would come back to Marisa's very gladly for a next stay!
