My family recently stayed at the Residence Corte Grimani for four nights. We stayed in a Superior room on the 1st floor and absolutely loved it. The two bedroom, two bathroom configuration suited my young family, including 1 yr and 4 yr olds. The laundry facility in the room was an absolute bonus. The windows overlooking the canal provided wonderful vantage points to observe the countless gondolas streaming past the hotel and to listen to the operatic tenors who performed in some gondolas. By the end of our stay, my 4 yr old daughter had learnt most of the words to their favourite song 'Ciao Venezia'!
The hotel is very centrally located in San Marco, and only a 2 minute walk to St Mark's Square, and a 3 minute walk to the Rialto Bridge. Located adjacent to a canal, water taxis can arrive right to the door step (tide permitting). This was incredibly handy with the children and all our luggage.
The staff were extremely nice, very helpful and provided great advice on nearby good restaurants which were kid friendly.
I would strongly recommend this hotel. We'll definitely be back.
