Location is perfect- if you want to be in the beautiful and hip neighborhood of Trastevere, this is your place! The patio is peaceful and relaxing. The beds are comfortable and our host was very accommodating and communicative.
The cons are that the bathroom needs updating- the toilet is in the shower space- not unusual for Europe- but it was rather damp and grimy. This was also the only bathroom, so if you are staying in the upstairs bedroom, you have to navigate a lot of steps to get to the bathroom.
Also, the kitchen is very basic, suitable for breakfast or a simple meal, but not serious cooking.
Overall, we enjoyed the location and the space, and our host was very kind.
