We stayed in the apartment for a week, communication was easy. Loved the terrace (9th Floor), air con worked very well and quietly. Tram 8/3 brought us to the most important sights, however only Trastevere / Testaccio are walking distance (great for foodies), the most famous sights require transport.
Even the linen was changed after 4 nights. Great Service.
Very safe Building and Supermarket next door.
Might come back soon!
