Stayed at the San Marco apartment for my birthday and it was absolutely perfect. We were met by Francesca who was very helpful and gave us lots of advice. It is in a very central location, we walked to most of the sites. The apartment had everything we needed and we were even given a bottle of Bellini as they knew it was my birthday. The singing gondaliers passing by the window was a real Venetian treat and the aircon was essential! Would definitely recommend this place.
