I would recommend this flat for mostly anyone on their first visit to Rome. It’s in a great location, very clean, beds and pillows were comfy, kitchenware was enough to make a small meal, and the hosts were absolutely wonderful!! They provided some snacks, excellent advice on site seeing, restaurants, gelato and public transit. The latter of which was especially helpful since the metro stops by the apartment are out of service until the summer of 2020. There’s a substitute bus called the Navetta that comes every few minutes though so it wasn’t that much of an inconvenience.
The photos do the apartment justice. Yes, the ceilings are low with the upstairs and bathroom being lower than the downstairs. I’m 6’3” (190 cm) and my wife is 5’3” (160 cm) but with some creativity we found the low ceilings to be manageable for our stay. I would not recommend the apartment if two tall people were staying together (> 5’11” / 180 cm) or for a really long stay; four nights was about the limit of our comfort.
Also, if you’re a light sleeper this probably isn’t the place for you as the street immediately outside is busy (buses, restaurants, etc.). We slept well though as we were exhausted after long days of touring 😴
All that being said, we spent about 4-waking-hours a day in the apartment and the rest out and about in Rome. If you plan on doing the same this is a great place to stay due to its location and helpfulness of the hosts!!
