This is a quiet, beautifully decorated apartment, with everything you could possibly need. The location is amazing - central and within walking distance to lots of cool neighborhoods and tourist attractions. The terrace is a really lovely and communication was fairly smooth with the hosts. There is also plenty of space. I feel like future guests should know that while the sleeping quarters are very delineated and private, they don't have doors - so kids in one sleeping area can hear everything that's happening in the master bedroom. I gave it 4 instead of 5 stars for two reasons. First, the fact that the flat was listed as being in Trastevere is in the title is misleading - the heart of Trastevere, and all its yummy restaurants, is a 10-15 minute walk. Secondly, the flat was a little musty when we walked in and doesn't have many windows. There is a heating device that helped in the bedroom, but the place could really use a dehumidifier. But overall, we were happy.
