The loft is really cute, nicely decorated, clean, and centrally-located. The neighborhood is amazing for exploring Rome with only 10 minute walk to St Peter’s, 15 minute to the river Tevere and to all well-known piazzas, and really close to both metro and bus stations.
The only minus point is the fact that there is no natural light in the apartment and there is humidity. As it is semi basement, the windows don’t open entirely (there are shields blocking the views of passengers and the sunlight), so you always need to have the light on. However, due to this it wasn’t hot at all, the apartment had a nice temperature of 20sh degrees. Also, there is the smell of basement humidity both in the hallway and a bit in the apartment (although significantly less in the apartment than in the hallways).
Altogether, really good place for visiting Rome for 3-4 days since the location is what matters the most for short stays.
