The flat is located in a wonderful place. Quiet but really close to every were in the Trastevere. It's like in the pictures, although quite used. I did not like that there was no elevator or comfortable stairs for the luggage (the stairs were a snail stairs very narrow) and also the contain in the bathroom was too old and dirty.
For the price I would expect new towels and maybe same wine or detail from the host.
My evaluation would be a 8/10.
