We are a family of 4 with 2 young boys. We really enjoyed our stay at Douglas's place. The condo was a good size for us but it would be tight with teenagers and I would not consider this a good option for 2 couples travelling together.
We found it very convenient for accessing the north and west coast beaches and relatively handy to restaurants and grocery stores. The condo was well-stocked with everything we needed and was very clean upon arrival. This unit is close to the pool and about a 10 minute walk to the beach at Turtle Bay resort (although we found that beach too busy for our liking and other than a walk down to the resort on our first day, did not visit it - or the resort - again).
There is a family living in the unit above. They are very quiet but we could hear every step they took and the toilet flushing - which is only a reflection on the quality of the construction, not on the family above. Douglas's unit also shares a wall with a neighbour - no sound came through the wall. So, overall, a very quiet location.
We appreciated having all the beach gear there for us and it was very handy to have the laundry facilities available.
Three minor improvements/additions that would be convenient for future users:
1) For indoor seating, only a 3-person couch and dining chairs are available. An extra living room chair for watching tv/reading in would make a nice addition.
2) A door mat and shoe rack would be very useful as there is no place to put shoes and the mat would cut down on sand in the unit.
3) Some hooks or a hanging rack to dry slightly damp towels and bathing suits. I realize the dryer is available but I some swim wear/rash guards cannot be put in and sometimes a slightly damp beach towel doesn't justify the use of a dryer.
