We've just spent a week at Concetta's apartment and can highly recommend it. We arrived later than expected at night, but were welcomed warmly. Concetta's daughter was very communicative and spoke English (apologies for our poor Italian!) The location was perfect. The no. 8 tram is a 5 minute walk away and basically takes you within close reach of most places of interest. We loved Trastevere for food, morning coffee and people watching......just a few stops away.
The local people were really friendly and helpful with us confused Brits, and that was a real bonus too.
The apartment was well equipped for food preparation and, having had holidays impacted by sleep issues, happily the queen size bed was very comfortable! Grazie mille :)
