We recently stayed at the Vatican Corner House twice and would definitely stay there again. The apartment is an amazing value for Rome - it's in a PERFECT location; it's very clean and modern, and is great for up to four people. Here are some specifics:

LOCATION: Ideal and very easy to find. Steps from the Vatican and an easy walk across the Tevere to all the tourist attractions. Some 2 hr parking in front for unloading bags.

BUILDING: You can't use the elevator to get to the apartment and it's up two banks of stairs. The terrace is fun, but shared with another family that is very present while you're there. Like many apartments in Rome, the space echoes and the walls are on the thin side, but our 11 month old was still able to sleep.

APARTMENT: Nice, light-filled and modern with TV, full kitchen, 2 baths and 2 big bedrooms. Well-stocked kitchen (they even left wine & a dessert on our second visit). Wifi was strong except for our second day when it went out entirely for most of the day. Caterina was very responsive to the problem. Main area has an AC (maybe heating?) unit; I don't think the bedrooms do.

BED/BATHS: Bedrooms were big with large, very firm beds. Apt includes linens, towels & face towels, toilet paper & shampoo/soap. Pillows had slightly crunchy (plastic?) covers, but overall beds were comfortable. Main bathroom is really nice for Rome - very big with a big shower, good water pressure and a bidet. Second bath is on the small side, but nice to have.

HOSTS: We didn't meet Cristiano - only Caterina who manages the property. She's lovely and speaks excellent English, and she was VERY patient with our changes, delays, cell phone issues and calls about the Wifi.

Overall, this is an amazing value for Rome. I'm not surprised it books up quickly.
