We loved our stay in Ca Farnese. It's spacious and comfortable, with everything you need (including a wheeled shopping bag, which was handy for taking the recycling and rubbish down to the collection point). There is one bedroom and bathroom on the ground floor, and a long and quite steep flight of stairs up to the main apartment (not suitable for anyone with mobility problems). It's located on a quiet residential street on the edge of the historic Jewish district, with lots of bars and restaurants close by (our favourite was on Fondamentadelle Cappuccine, and that whole area is quite lively). Fondamenta di Cannaregio is good for having a drink and watching the sunset. The vaporetto stop (San Marcuola) is a short walk. Our host, Federico, was very helpful. I would highly recommend this apartment, and would definitely stay here again.
