We've spent 2 nights here in March. The room is tidy and comfortable. The shared bathroom is also very clean, the kithen is well equipped.
The location is awesome, in the middle of Venice, you can reach literally everything by walk or by vaporettos.
Mirco is a great host, helps with everything! The day before our arrival he sent a detailed message about how to reach the appartment (with pictures), how to check in and a list of recommended places to eat. I highly recommend you to stay here. Thanks for having us!
