This is a fantastic apartment, spotlessly clean, well-appointed with lots of details (really feels home away from home), with fully equipped kitchen, nice patio. Location is great as it is outside the tourist infested areas but it is still walking distance to all sights.
There are three minuses: it receives little sunlight (as it is on the ground floor), it is not soundproof (the upstairs neighbour's three-year-old is training to be an indoor marathon runner, and street noise is loud, though there is not much traffic. However, we could have slept in the den if it really bothered us and we did not.) Finally, the Internet connection is dreadfully slow. We have complained about this repeatedly but at no avail.
Nonetheless, the pluses greatly outweigh the minuses. Caterina has been extremely helpful and quick about everything (except the Internet issue).
