You'll want to read all of this. Overall I'd say we had a good stay, but a couple of issues were just too jarring.
The good:
The apartment was well-furnished, and the living space is a cozy place for friends and family to gather around for meals and chats. The location was ideal - we were a 1-minute walk from Rialto bridge, 5-minutes from Saint Mark's Square, and there were shops, restaurants and ATMs in the vicinity. The apartment is air-conditioned, which is a MUST-HAVE if you're visiting Italy in the summer. The kitchen is well-equipped.
Potential issues:
There is only ONE bathroom meant to be shared between up to 8 guests. While my group of 8 (young adults) didn't experience any problems with this, other groups might.
The apartment consists of a total of 4 floors. This may pose a problem to the physically challenged.
Also take note that you'll need to pay a visitor overnight tax of €4/person/night for up to 5 nights during your stay in Venice.
The bad:
VERY LATE CHECK-IN. Venice Apartments (the host) sends out forms to ask guests about their check-in details (including ETA at the apartment, mode of transport) which would really give them a very time-accurate picture of our journey. My group of 8 followed all instructions, updated the host of our location at the appropriate times, and even arrived 10 minutes before the scheduled check-in time. However, the host only managed to let us in MORE THAN 1 HOUR LATER with our luggage in the street. The reason they provided was that the host needed to 'check-in other guests on the other side of Venice'. As much as I understand that the host has many properties to handle, this is ultimately unacceptable because: 1) the delay was too long - we missed a scheduled tour; and 2) this COULD HAVE BEEN AVOIDED if the host had used the information we provided to warn us that our preferred check-in time was not feasible and contacted us to reschedule.
WATER LEAKAGE. On our third and last night there, Venice experienced a heavy thunderstorm such that water began to seep into the apartment from our second- and third-floor door-windows. The first-floor air-conditioning unit began leaking water too!! Luckily a couple of friends were home at the time to fight the flooding with bowls and towels. The first-floor AC did not work that night and two guests had to sleep in sweltering heat.
