We (family with 2 teenage kids) spend 4 days in Rome. Mary's apartment is a perfect base for visiting the city: very close to the metro and the shops nearby (bread around the corner!). Nice bonus is the garden, which we used for our breakfast every morning.
The apartment is not very large, but very well equipped and the wifi works good. Mary is a perfect host, she is very precise at her appointments and she even arranged our taxi to the airport. The double and single bed upstairs are good, but the sleeping couch downstairs needs replacement.
