I stayed for 2 nights at this place. I only went there to sleep but it was perfect! It has washer/dryer and there was detergent available. Jacopo also left some cookies to snack on. We left the apt earlier than check-out time but Jacopo offered to be flexible in case we needed to stay a bit later. That was very nice.
I definitely recommend this place and would stay there again if I ever go back to Venice.
Getting to the place from the Santa Lucia train station involves a 15-minute walk and it involves going up and down stairs. This was not an issue for me but I think people need to be aware of this if having big luggage to carry or having mobility issues.
