Haydee was awesome. She met us at the taxi stop and took us the apartment, which was beautiful and clean. She had snacks for us along with a refrigerator stocked with water, Coke, and wine, which was a pleasant surprise. The kitchen and living room are spacious and there's a nice patio as well.
The apartment is close enough to San Marco without being overrun by tourists.
The only point I'd make is that the third bed is s single bed, and the fourth bed is a medium sized couch, which could fit maybe an adult up to 5'8". This would be perfect for one couple and up to two kids, but a bit tight for two couples.
