Federico's place is great, very large space with huge windows to a beautiful view from a top of a hill.
communication was fast from Federico & staff. we met Grace that welcomed us in the late checkin and she was Awesome!!
there is a cleaner every day which is a nice surprise.
location is good, very close to the main road with train & bus station (about 200 meters down the hill)
super close to the big flea market for Sundays.
about 15-min walk to the main area of Trastevere.
note that there is walking up the hill to get to the apartment, we felt that the apartment & view was worth it!
only issue to note, regarding the bed, it is a double bed - two seperated mattresses connected so the middle of the bed is a bit lower . Each mattress is super super comfortable on its on, and the pillows as well :))
