Location is right in the middle of Trastevere - great starting point for walking. It is a bustling neighborhood, but the apartment itself and the patio are very quiet because it faces the interior of the block of buildings.
Apartment has great air conditioning unit, and has good space for sleeping/hanging out. The bathroom is VERY small, and the shower is essentially in the sink. The shower drain is slow to drain as well, so be aware when multiple people want to shower in one morning.
