The view from this place is amazing, and the location is so convenient. We stayed here with 2 small kids (and my partner sprained his ankle), so it was really helpful that we didn't have to walk far to get to public transport. There is also a playground nearby.
However, it was quite tight for 4 people, even though 2 of them were pretty small. The bed was just a double bed, rather than a king bed as advertised, and the futon is on the small side. They did not provide towels for 4 people, and the linens for the futon were buried in the back of a closet. This would be a perfect space for 2 people, but really should not be advertised for 4.
Also, as mentioned before, the "air conditioning" does not work. There is a great breeze off the water which we enjoyed during the day, but we could not take advantage of this at night for several reasons: 1) The only way to open up the place is with the patio doors. There is a sidewalk that gets a decent amount of foot-traffic directly next to the patio, so for security reasons it did not seem smart to leave those doors open; 2) there are several very bright street lights right outside, so there's not really a practical way to block the light with the doors open; 3) buses use the area in front of the unit to turn around (as in, they pull up in front of the unit and you are literally eye-to-eye with the bus driver, which greatly amused my kids during the day as they tried to see which drivers would wave back, but did leave you with a feeling that a bus was about to drive through the front of the unit) - so with the doors open there were frequently headlights shining in and then the reversing beep. We did not find the buses to be an issue with the doors closed, but as a consequence the unit got quite stuffy at night. Just having a fan would have been much more effective than the "A/C".
