We really enjoyed staying in Castello - the area is close to the centre, very peaceful and relaxed, but also bustling with Venetian family life. We were in Venice for the Biennale and both the Arsenale and Giardini were only a five and ten minute walk, as were a range of friendly restaurants and supermarkets. The apartment was perfect for our short trip, it was nicely decorated, spacious, and had excellent wifi which is essential when travelling with teenagers and not always possible in Venice. Thanks for a great trip!
