Dontatella's place is a good choice for anyone looking into a Venice vacation. It's located on a bit of a sleepy street that is perfect to come back to at the end of a long day of site-seeing. Check in went smoothly and was facilitated by a very kind upstairs neighbor who didn't have a strong grasp of English but spoke French and Italian fluently.
The only downside is that the air conditioning is a bit on the weaker side and is not located inside the bedroom. This is typical for much of Italy, but it did make some of the hotter nights a bit difficult.
The wifi also cut out from time to time, but I'm sure that this is a fixable situation.
Overall we enjoyed our stay!
