This apartment is exactly what they represent in the listing. It is HUGE! The apartment is truly in the *heart* of Trastevere, which is really fun as a tourist. That being said, if you want a very quiet apartment this is probably not the one for you. In Italy, folks seem to stay out having drinks until 1-2am even on weekdays.
The apartment is well appointed. It is really nice having a nespresso machine for coffee in the morning. There is an AC unit in the bedroom only. The building does have a VERY small elevator (not large enough for a wheelchair) which is helpful for getting luggage up.
I was able to check-in a bit early, which I really appreciated from the hosts.
Oh and there is a (paid) luggage storage business literally across the street. So if you arrive early or need to check-out and aren't sure what to do with your bags, that storage is really fantastic.
