1) Definitely not a large enough space for 5 people. We had three people there (two adults, one child) and were very cramped. Once the air matress is blown up, there is almost no floor space left to even navigate to the very tiny bathroom.
2) While A/C is advertised, (and was important to us) visitors have no access to the actual A/C (or heat) controls. You only find out in the details provided right before your trip that the A/C and heat are controlled by the unit upstairs. The A/C was not turned on for our visit in mid July and it got very hot for us, especially at night. That made our stay less than comfortable.
3) The bed in the rental must not be a full size bed; I am 5'3" and my feet were at the very end of the bed; anyone taller trying to sleep in that bed would have their feet hanging over the end of the bed.
Overall, without temperature control (no way to access A/C or heat) and with very cramped quarters for three, and a very small bed, a hotel stay would have been a better choice for us for the money.
