Our stay was absolutely wonderful in all respects. Sonia took great care of us and responded to our emails very promptly. Our arrival time was delayed significantly and even though we arrived very early the next morning, we only had to wait a short time for someone to arrive to check us in, and never felt like we were a burden.
The apartment is decorated in a very lovely and classy way. The old piano in the common room is a particularly nice touch. Our room was exceptionally clean, with great views over the lovely courtyard. Our bed was also very comfortable.
The additional amenities were superb as well. The common room has couches, tables, computer, and cooking facilities. One evening a couple and young child made dinner on the stove and they looked as if they had everything they needed. The breakfast was a delicious assortment of cakes, cereals, juice, milk, tea, and coffee. Before I arrived, that sounded pretty basic compared to my thoughts on American breakfasts, but it was very good and suited us just fine. (Also cake and milk make for a great late night snack)
The building is in a great location. Easy to catch the tram, bus, or metro and is just a few minutes ride from the Colosseum.
All in all, I highly recommend this place to anyone. For the quality of the amenities and room, the location from the city center and neighborhood, and the outstanding, personalized service we received, this place is perfect. And with all that, you can't beat the price.
