Very good experience!
We stayed a full week for the Venice Biennale in end of April.
Saifs place is 1min walking from the main station for busses and trains in Mestre and this means you reach Venice in less than 20min everyday and night. But also the infrastructure next to Saifs place is very good. Supermarkets and restaurants in case you need something are just around the corner. The place itself seems totally new, modern, safe and good equipment and he is doing everything to keep it in that condition. It is very clean and comfortable. Highly recommend this host!
