Our stay at Marina and Gianni's place was great. The appartment is a bit smaller than we expected from the photos but travelling as a couple without the kid it pretty much answered all of our necessities. The kitchen is very tiny, so cooking something more than an egg is a bit tough - if you are planning on sustaining yourself on bought groceries, be ready for a little inconvenience. It DOES have all you would need though (even a capsule coffee machine).
The heating is super convenient and the constantly present hot water is great as well
But the BEST reason to stay is the location - most of our favourite spots (trapezzino, bar calisto) are a minute's walk away. The whole neighborhood is exactly what we were looking for.
The apt is rather quiet, but the neighbours tend to argue/fight during the night. Didnt disturb my sleep much, but if you are a very light sleeper - might wake you up.
In general - a pleasant stay, undoubtedly worth the price!
