The appartment is easy to find, in 5-6 minutes from Ottaviano Metro Station. Just across the road from the Vatican wall. It takes 3 minutes to Piaza San Pietro. At the entrance to the building is a place with the best ice cream in Rome. :) At the corner of the street is a good restaurant with a very good traditional cuisine. For Italian-style breakfast you can find cornetto e cappuccino at the corner of the street. A Carrefour market is in the neighbourhood.
The appartment is recently renovated, set in an old-new, tasteful combination. The kitchen is very well equipped with everything needed. Patrizia, Fabrizzio and Gian Paolo are the perfect hosts: they welcomed us warmly, offered us the traditional limoncello, fruits and all their kindness. During our stay we communicated easily and efficiently.
I recommend the appartment with all the confidence. Have a nice stay in Rome!
