Marina is a great host though she was late in checking us in by about an hour where we had to wait outside the building. However, she had the porter let us in to the apartment and we had to wait for her to come by to explain/show us around. Marina was very helpful with tips on how to get around and about the city [beware of pickpocketers,etc].
The apartment is a spacious bachelor pad with kitchen and an amazing balcony. Perfect place to stay for a few days as you can take advantage of the kitchen and balcony area to have a quiet dinner or lunch.
Overall experience was great with this place. The Vatican is literally 10 minutes away, the metro was also close by about 5 minutes and the supermarket was convenient too.
It was a pleasure staying at Marina's apartment.
