The apartament is in great location - walking distance to all the Rome's attractions - right between old city and Vatican. There is plenty of space for a large family or group of friends and two bathrooms are a big plus. We travelled in winter so diod not need it but the AC units are everywhere and heating (in winter) works great as well (excluding kitchen). Communication and check-in process were superb. Place is equipped in all one needs (plenty of towels, kitchenware, even umbrellas)
This being said, there are some downsides: the "old charm" of the apartment could use some new paint and repairs. Some furnitures - renovation. Place is quite dusty, feels a bit cluttered. Pictures on ABB are well lighted and staged so in real life be prepared for a slight disappointment. The very few windows the place has all lead to a small and tall courtyard so the apartment is VERY dark. There is a stairway leading to open mezzanine in the main bedroom but the mezzanine itself serves a a clogged storage.
Overall - as low season price was quite attractive, price to quality ratio was good. It was a perfect location for a 3 day sight sight-seeing trip with only few slight downsides.
