Francesca and Cristian's apartment is absolutely amazing. Everything is brand new and very modern, and there is plenty of space, even with 4 people. During the summer, having 2 strong AC units is so great.
Murano glass accents are all over the apartment, including chandeliers and figures. All are made at Cristian's glass workshop on Murano island.
The location is great too, away from the crowds in St Mark's but still only a 10-15 min walk away. Venice itself is very walkable, so you can actually walk to most things in less than 30 mins.
