Our family of four was very comfortable in this apartment - two adults and two teens.
The spacious apartment is beautifully appointed and within perfect location to tour Rome and away from the crowds - 3 min walk to metro station, 15 min walk to Vatican and if you prefer a scenic route to ancient Rome sites (rather than metro) 25 min walk. A large choice of restaurants also very close to apartment. We visited in mid July during a very hot week and the AC made the apartment a comfortable retreat during hot times of the day.
Miguel and Barbara were great hosts with communication before our stay helping us secure airport transfer and proactively sent us recommendations for places to eat and visit. Their hospitality is next level!
