We had 4 nights at Patrick's apartment.
The location is great, you are yards from St Marks Sq but once up on the 5th floor you are away from all the hustle and bustle . It was very hot so the air con was greatly appreciated.
The apartment was spotlessly clean and we had everything we needed. The kitchen is small but was adequate for us as we ate out every day. The terrace is a sun trap and you can see St Marks Sq from it. We would recommend getting the water bus to Murano and Burano, St Marks Basilica and the Campaniles in both St Marks and across the water on San Giorgio. My main tip though would be just to wander. We did it and whichever direction you go you stumble across scenic alleyways, hidden churches, bridges and then you come out into a square with restaurants and bars
Great city and would recommend Patrick's apartment.
