The flat is nice and well-finished. The location is perfect for a weekend in Rome (in Piazza Re di Roma there is a super good Cannoleria, check that out!) and the apt is located in a very beautiful and peaceful palace. The apartment has all that is needed for two people, including kitchen tools, pans, and pots.
The apartment is really small, even more than you can grasp from the pictures. Moreover, there is only a very small window. On top of these general remarks, the following comments might be partially due to the fact that we visited the apt in the coldest days of the year (it even snowed!): the amount of hot water available for showering is rather limited (no more than 1 at a time); the heater is located upstairs which creates a big difference between the temperature downstairs and upstairs.
Overall, the quality/price ratio is optimal and if you are looking for a nice place to visit Rome for a weekend it is definitely a spot I would highly recommend
