The positives: the location is great, near San Marco and the Biennale, in a quiet courtyard. The place is very clean and pretty spacious.
The negatives: one of the bed squeaked whenever I turned, so I couldn't sleep well. The place could do with a few more amenities, such as a kettle to make coffee/tea with.
Overall: the place is good on the most important points, but could use some improvement on the details.
