We spent 5 days in Rome in this apartment - perfect location, only a few minutes walk to Peter's square and in the other direction to the metro station. Shops, grocery store, bakery, restaurants, cafes, everything is literally only a few steps away...
Two bedrooms with double-beds each, hence perfect for us, a family with two kids - a spacious living room, a well equiped kitchen (dishwasher and laundry machine), a nice bathroom with a "walk-in shower". Everything was working fine (including wlan access), no issues encountered at all (here and there you see that the furniture is not brand new, but there is no impact on the functionality), two sets of keys were provided (so this flat would be a good choice for two couples as well), check-in around 9:30PM was no issue either.
Communication with the host worked well - highly recommended apartment for anyone looking for a fairly priced "homebase" for a few days of sight-seeing in Rome.
