We have never met Federico but he communicated very well. Michaella met up with us and showed us around, gave us really good recommendations on restaurants and gelato shops using maps and gifted us complementary bottle of Sangiovese which was so lovely! The location is just can't get any better! Only a few minutes walk to Campo dei Fiori and Piazza Navona, supermarket, coffee shops and restaurants yet very quiet at night. Ice cold A/C was a huge plus!! Even though you have to go through 4 doors and some stairs, it is totally worth it. Only wish was to have instant hot water. We barely had enough hot water for 3 mins quick shower and had to wait 30+ mins to get more hot water each time and trust me you need to shower everyday in the hot summer time in Rome!! Other than that, Federico's apartment is highly recommended:)
