Sandra's apartment is a great base to visit Venice. I'd happily stay again on a return trip to Venice.
The apartment is well-located - about five minutes from Rialto bridge - although it normally took more because the Venice Calles are confusing. There's a well-stocked supermarket about 200m away although I only bought breakfast stuff as I ate out - too well! - every night.
The apartment was ultra-clean, quiet and very light in the bedroom - the rooftop view is from the bedroom. The stairs were only a challenge on arrival and departure with a suitcase. The rest of the time they were no problem.
I had a problem with the shower which her husband fixed the same day.
