My wife and baby stayed 3 nights in this apartment. I highly recommend this for a few reasons.
Location: a few blocks from the main square and all of the best food. Couldn't be better.
Space: the apartment itself is super spacious and great for families. Mattia even offered to set up a crib for us and a high chair was provided.
Amenities: everything you need is there including dishes, fast internet, etc.,
Host: Mattia was super responsive and helpful. He was there as promised for checking at the time we agreed. Everything went smoothly.
