Frederick and Annarita's apartment was great for a family of 8 adults, 1 toddler and a 10 month old baby. There are more than enough rooms and bathrooms for everyone. The location is VERY close to all the major sites and landmarks (within a 5 minute walking distance). It can be a little noisy from the streets at night, and you can hear the cathedral ring its bells in the morning but it wasn't bothersome.
There is no lift but a short flight of stairs. Lots of great restaurants to choose from as well around the apartment.
Annarita was extremely kind and patient even though we had two screaming babies with us! Thank you Annarita and Frederik for letting us stay in your place - it was perfect.
