Nice apartment at nice location!
We stayed 3 days in Pinas apartment at the start of October. It is in really good location next to San Giovanni metrostation (A and C-lines, about 200 m walking). Also Colosseum and Forum Romanum was near (little bit more than 1 km, 20 min walking)
There were 8 of us: grandparents, parents and adult children. We fit in nicely in 3 bedrooms!
Pina is wonderful hostess: she answered all the questions fast with Whatsup, give good advices and even booked taxis for us! Really 5 star!
