We weren't expecting anything special by booking here but we recieved quite a lot : the room was very nice, clean of course, but also well located in Rome, the beds were excellent, everything related to equipment was good.
But the best comes from the greeting, which was both warm and convenient for us. Thanks a lot, Anna, and if we come back to Rome, be sure we'll be back to your guest house ;)
I highly suggest to anyone to book here.
