Antonella's apartment is very clean, well equipped and comfortable. Yes, it's small, but I travelled alone, and it was enough space for one person. The location is close to ideal: most of historical sights are in walking distance, metro station is in 3 minutes walk, Termini -- the main Roman rail station -- in 10 minutes walk. Antonella lives the next door to the apartment and she is always ready to help and to answer the questions. I had a great one-week stay and highly recommend this apartment, especially for alone travellers.
