Positives: the apartment is spacious, incredibly clean, quiet and has beautiful views out over the surrounding houses. We had 2 kids with us and it's a good child-friendly apartment. It's also very central, a 10 minute walk to Rialto bridge and many cafes/restaurants and close by. Wifi very fast.
Negatives: the person meeting us was not there when we turned up despite messaging him several times beforehand confirming the time. I ended up ringing him and he arrived 25 minutes later. We had children with us and this delay made a big difference. He also couldn't answer specific questions about the apartment ie. where to put the rubbish! You have to climb up four lots of very steep stairs, tiring even for a fit person!
