My friend and I had a really lovely stay at Sabina's place. The apartment has a old style charm that is very appealing and relaxing with lovely old pieces of furniture. We were very comfortable and slept very well in the apartment. Given the temperature, the AC was a godsend. There were also most necessary things in the kitchenette, so we could make coffee or tea in the mornings. The highlight, is the little terrace so you can enjoy a bit of outdoors.
The location of the apartment is really great, close to the main train station, 5 min from shops and within walking distance of the Flavian Amphitheatre (we learnt this is the real name of the "Colosseum")
We also had a meal experience at the flat where a young chef came and cooked a 3 course meal from a menu agreed to beforehand. Def worth a try and nice to do at the flat after a day of running around Rome.
Note the flat is in the attic so you should be fit to climb stairs.
All in all a great stay and would recommend
