Not sure it’s quite a palace but it’s certainly a very beautiful and luxurious feeling guest house. This is a 5 Star b&b be assured however be aware that they do not have euro to Italian adaptors, you must bring your own and there is many stairs, although staff is willing to help when they can and this is typical of Venice. I highly recommend this place as it is close to the Fondamente Nove (f.te Nove) waterbus station where the aéroport shuttle can be taken, the centre and several very nice restaurants on the street.
