My family (two adults, one teenager) had a great two-week stay at Anna and Marco's!

Pros: clean, spacious, nice views, access to city amenities and also to the parklands south of the city...all on foot if you like to walk, or via metro if you don't.
Cons: hard to think of any, but do consider the stairs--we 50-year-olds did fine with them, but if you have a bad hip or some such issue, they could be limiting.
We'd go back without hesitation.
