Lovely little flat, super close to the Vatican and close to the Trastevere area. If you are happy walking up to 40 mins or so it is certainly within walking distance of everywhere - we didn't need to use the metro or taxis during our stay.
The flat is lovely, compact - but great as a base to explore from, comfortable and clean.
Evelina was so helpful and recommended places to find some food when we arrived on a quiet Sunday afternoon.
