This apartment is a great find!
We stayed in April as a party of 3, which was perhaps a little tight, it would be better suited to a couple.
Only 'groan' would be that as 3 ladies there wasn't enough mirrors (there's only one in the bathroom) which made it tricky to do hair etc.
Only other 'thing' to note is that due to the regulations set in Venice (NB-not the owners), is that you need to put your rubbish out between 6-8am each morning which is an early start.
