The apartments are ok for a short stay, but for a long stay journey I wouldn’t choose them.
Pros:
1) Good location. It’s easy to walk either to Vatican or to the Pantheon
2) Marvelous view from a terrace
3) Good working air conditioning
Cons:
1) Broken shower. Cold water and low water pressure
2) Apartments weren’t prepared for our arrival and were dirty after previous guests. It seems that a host is uninterested in welcoming guests and just get benefits from apartments
3) Tiny and inconvenient bathroom and dirty mirror
4) The whole apartments are small even for two persons. A spiral staircase to a kitchen is very narrow. Not very comfortable, furniture is old.
5) Wifi is slow and is unreachable in a kitchen. Seems that access point is shared, some kind of 3G and located outside the apartments
6) No vacuum cleaner for a simple clean. It’s important especially for a long stay journey
