Daniela's place is very nice and very conveniently located. We walked a lot in 3 days and the apartment is close to St. Mark's Square along with almost everything else you would need/want to walk to.
The apartment was absolutely as described and was clean and Daniela provided everything you would need! She was a great host and was very quick to respond to any messages we sent her and she was very helpful with transportation tips!
Don't forget, as the description describes, there is no elevator and it is on the 3rd floor. All luggage will need to be carried up those stairs, but it only needs to be done at the beginning and end of the trip and it wasn't too bad.
