I thoroughly enjoyed my stay at Valentina's apartment. The entire unit were separate rooms with private bath and kitchen. The elevator is a plus. Valentina made sure that I had fresh towels daily and was so nice to provide some food and water each day for breakfast. The place is clean and airy.
She also made arrangements for parking for an extra charge although I would recommend not bringing a car since the Vatican is a 15 - 20 minute walk from her apartment and close to the metro station.
There was internet connection, however I found it to be too weak but doable.
