Stayed here with my wife and two boys (8 & 11) for seven days. The host was responsive to all messages and also left a very useful book full of tips about the local area that was accurate and useful. The location is very good everything you could want within walking distance (easy access to major routes to main attractions in San Diego - Uber ride to Gas Lamp was just under $20 when we wanted to leave the car (20 mins)) and extremely peaceful in the evening.
We could see our kids playing on the mission bay beach (20 metres away, which is fantastic and not crowded) from the terrace and also walk one minute to the amazing beaches and boardwalk on the ocean side of the bay.
Spotlessly clean with a high standard of fittings - this house is reasonable value for money in every way. Would be surprised if anyone renting is disappointed.
Only criticism would be that the pictures do not do justice to the space, quality and location :-) This house is a winner!
