Really awesome location. Walking distance to tons of restaurants and bars. Also about 25 min walk to colosseum and historic Rome and 30 or so minute walk to Vatican City. Only downside is if you are a backpacker is that it is not really walking distance to any train stations. The closest bus is a public bus so there is also not much room for big backpacks and the busses fill up really fast.
Luisa is very gracious. She let us store our luggage there early before check in and was very responsive and accommodating. Bed was comfortable and AC was in room if needed. Great little place in Rome.
