Alessandra's apartment is really great: spacious, well organised ( 3 bathrooms, a real plus), efficient and quick to respond airco, very good bedding, very well positioned (yes, it is in Trastevere, but North East of it, at Ponte Sisto, which means short walking distance from P Navona).
Costanza has been very nice, flexible and efficient, before our stay and for check-in (we had to change last minute because of our flight being cancelled) and check out process.
Thanks, we recommend it for sure.
