Excellent visit in Tatiana's apartment! Location is perfect: close to city center yet not too close, also is on the 81 bus line which goes to many tourist places including Coliseum and the Vatican. The secured parking was about 400 meters away in a garage which worked well and we also had a second car parked outside the apartment and it was fine. The neighborhood is safe and nice.
The apartment itself is excellent. It has windows on both sides of the building so opening windows left a very nice breeze through at night--we didn't even turn on the air conditioners and we stayed in August. Everything in the apartment worked as advertised and they had clean towels and bed linens ready for us on arrival. The apartment is on the eighth floor, so it has great views looking over the city (and the lift works well, too).
Tatiana arranged friends to receive us into the apartment and did a great job ensuring we had everything we needed. They were polite, professional, and very helpful. Spoke great English, too (unfortunately we don't speak Italian so was happy they accommodated us).
Very good visit. We'd like to stay again.
