Luigi's apartment is spacious,clean,and has all the amenities you need for a beautiful stay in Trastevere. There is air conditioning in the bedroom now, as promised in one of the reviews below.
The location is excellent. 15 minute walk across Ponte Garibaldi to the centro storico and right off both P.zza Santa Maria and P.zza San Calisto,which is a great spot for a nightcap after an evening out in the city. Lots of locals hanging, lots of great people watching. Although others mentioned the noise from the piazza being a problem at night, we didn't think so at all. Perhaps because they were in the pre-air-conditioning era of the apartment,so the windows were open.
We couldn't have been happier with the apartment and the experience. Thanks, Luigi!
