The staff were very welcoming from start to finish. We received a message before we arrived with details on how to find the apartment and any other info we needed prior to arising. Vatican City is less than a 10 minute walk (could see the basilica from our window), and all other main attractions about a 40 minute walk or 30 min bus journey, however we found that the walk was very lovely and allowed for extra sight seeing, so we only ended up taking the bus 1-2 times (bus stop is very close too).
There is also an array of convenience shops, souvenir shops, restaurants, cafes and dessert spots dotted around, all of which were delicious and had great staff.
Would 1000% recommend staying here during your visit to Rome, could not find a single fault with our stay as the staff were super accommodating and flexible, and the location was very convenient. We also felt super safe as 2 girls staying together as the entry to the apartment had several locks.
