This is a beautiful apartment just off the very busy tourist track. Close enough so you can be part of it all, but you can still find areas that are quiet.
I would recommend this apartment to either a family of 4 or 4 people max. The loft is really not a sleeping area unless you were desperate, my kids refused to sleep up there and it was one of the things they were excited about prior to arrival.
Make sure you only have the minimum of luggage, this can be said for all of Venice, there is a left luggage at the railway station on platform 1.. use it, it is expensive but the best Euros you will spend in Venice. The apartment has about 4 flights of stair and you feel it carrying heavy luggage and that doesn't include the 3 bridges from The Rialto to the apartment.
I hadn't been to Venice for about 12 years and then prior to that 20 odd years. It has changed, early winter there was hardly anyone around, it was hard to get a meal.. now it is the opposite, it is extremely crowded, thousands of tourists and except in the early morning total bedlam. If I realised how crowded it was at this time of the year I would have changed plans. This is not to say I would have changed apartments. I will be back but will be asking when to come, certainly not the first week of January. Many thanks Elisabetta and your staff.
