Perfect choice for your stage in Rome! We were 6 days in Mary's appartment, which is very nice, clean, big enough for 6-8 persons and even longer stages. It is in walking distance to the Vaticane, bus and metro stations. Nice restaurants are very near (e.g. Il colibri or l'isola della pizza), if you're tired from walking ;-)
The organization was very good, of this 5 star appartment. Best appartment booked ever here! Thank you Mary!
