I was in Rome for a very short time and needed a place just for one night. Dina's room was just right for me; it was clean, quiet, private, and with fast wifi.
She was very nice to make it completely easy for me to meet up with her upon arrival even though I had to change my plans and arrived 4-5 hours later than originally planned. And she seemed very professional and sociable. The apartment is 30 minutes walk from Colosseum and about 5 minutes to a subway station. So it's very easy to get around.
