The apartment is in a great location - though this means that you need to cope with crowds of tourists as you make your way to and from.
The kitchen is well equipped and you should be able to cater for yourself should the need arise.
Shopping for groceries can be a problem unless you know where the local stores are located. I used the Coop stores - check for their location on google.
Get the host or their representative to tell you what to do with the garbage.
WATCH OUT FOR THE STEP FROM THE BEDROOM TO THE BATHROOM - if there is no foam barrier - place a book or some other appropriate object to warn you/soften impact
which may occur if you go to the bathroom during the night!
If your arrive by bus or train - be aware that it is a 1.5km + walk to the apartment. Best option is to take the vaporetto to Rialto and walk from there.
