Elisabeth was a great host and her apartment was perfect for what we were looking for.
She provided us with maps and a personal drinking/eating guide. She works out of the studio during the day which was great because we could ask her questions if we wanted or have out on privacy while she was there too.
The room was great. Bed was nice and firm just how I like it. Water pressure was amazing and never had an issue with hot/cold. She had beer, water, coffee and tea available near the entrance to the studio.
After walking to most areas of Rome from her apartment I'm confident this is the best location you could possibly stay in. Trastevere is a really cool neighborhood. We ate our best meals there and had the most fun at night there as well. You get to avoid the overly touristy areas when you go home at night and you get to be immersed in the local feel.
Would definitely recommend!
