I have been at B&B Giardini with my family of 4. We arrived late and the owner met us at boat stop, helping us to buy some food in a restaurant which was still open. According to what we had read in the website, B&B Giardini is a little niche full of hospitality and the location still maintains the features of the old Venice, just fifteen minutes on foot to st Mark's square, full up of shops, supermarkets and small restaurants. The accommodation is modern, clean, silent and very cozy, newly furnished with nice facilities such as a kitchen which has everything you need if you want to cook your meals and this is important because restaurants are rather expensive in Venice. We saw the venetians wake up and buy their vegetables from boats nearby. It's nice as a visitor to feel part of a community. Excellent communication with the hosts prior to visit. A very good place to stay if you're looking for a place where to feel at home and the price is reasonable comparing with the average rates in Venice.
We would certainly recommend this accommodation.
