As per other reviews, Caterina/Valentina's apartment was a really great place to stay and explore Venice.
Comfortable beds, modern bathrooms and kitchen and a large airy lounge made staying here a joy.
The best thing about the apartment for us was the location. Giardini was a quieter area of Venice but with great access via Vaperetto to all the key attractions.
We recommend getting the 3 day or 7 day Vaperetto pass so you can just hop on and off and save your walking for the back streets.
We loved Murano, Burano, the Lido, Peggy Guggenheim museum and just wandering the back streets of Castello.
Caterina and Valentina couldn't have been more helpful hosts. We highly recommend staying at their apartment if you are planning a trip to Venice.
