Everything about Boni's place was first class and five+ star! Boni and Max are excellent hosts, amazing people, very classy, very friendly. They know a lot about Rome, and gave us great tips on where to go and where to eat.
The property is in a great location, on a quiet, safe street with a doorman. The unit is on the 6th floor, with plenty of light, plenty of privacy, and, of course, a large terrace. The rooms are large and comfortable, furnished with high quality furniture and accessories. There are 2 bathrooms, which was helpful. The kitchen has excellent equipment, and it was a pleasure to cook at home. The first bedroom has an AC unit. The main room was very large and comfortable, very nicely appointed.
Bus lines are a few steps from the door, the metro was about a 5-minute walk (as in 300 seconds, not an Italian 5 minutes). There is a restaurant downstairs and a bar across the street. Termini is a short walk, if you are so inclined.
We did have one problem -- the apartment was so nice, we never wanted to leave!
Highly, highly recommended.
