Christina's place is just perfect.
Make sure you bring wine and pasta because you're not going to want to go out. The terrace was the best place to sit, eat, drink and relax. It's utterly magical.
Christina is terrifically helpful, knowledgeable, generous and available. You're in very safe hands.
It's in the middle of everything without being in the hell that is St Marks, etc. the neighbourhood is charming and everything is only a couple of mins walk away.
