Luisa was a wonderful host - we were met at the train station and walked right to the apartment. Great location, with lots of cafes and canals almost right outside the door. All was as advertised.
One small layout quirk - second bedroom requires you to go through the first bedroom, and the AC is only at the entranceway, so when it's very hot outside, it's a little warmer than one might like in that bedroom. That wouldn't stop me from recommending the apartment, but it's something people should be aware of for when it's very hot.
That aside, we had a great stay. Loved Venice!
