Marcos place was perfectly located in a neighborhood that is very closed to San Marco, but far enough to avoid the mass tourism. It can be reached by boat from Santa Lucia which offers a great first impression of Venice by boat ridding!
It is also 3min walk to Biennale which was a great incentive for me and my children to go and see some great art projects in a beautiful setting. The eating in general is quite expensive for the quality of the food as compared to other cities in northern Italy. That of course has something to do with Venice being as touristic! We used the local Supermarket a lot and had some nice dinners in the house, which was great. We have some difficulties with noice at Marcos place which is maybe part of the Venetians culture and tough for Marco to control. Overall a great spot for a short visit in Venice.
