Four: the queen bed in the room and the loft bed up top. If you need more space, the other rooms can be booked alongside it.

Your room is yours, behind its own door code. The kitchen, the dining room, the living rooms, the laundry and the yard are shared with the guests in the other rooms, and Marty keeps them spotless.

Yes: book two or three rooms side by side, or take The House on Frink and have all 5,000 square feet to yourselves, for up to 14 guests.

Check-in is from 4 pm and check-out is by 10 am. Every room has its own door code, and the front door has an electronic lock too.

Yes, parking is free and easy at the house. The 805, the 163, the 5 and the 15 are all a few minutes away.

A daily grab-and-go breakfast is set out in the kitchen, along with coffee, tea, fresh fruit and snacks through the day.

Yes, the house is pet friendly, with a daily pet fee of $10 to $15 depending on the size and type of pet; tell Marty when you book, as undisclosed pets are $100 a day. The back yard is artificial turf, so dogs go for a walk instead: there is a park about five minutes’ drive away.

Yes. Beach chairs, umbrellas, towels, boogie boards and snorkel gear are free to borrow; ask Marty and she will set you up.

No smoking, no parties or events unless the whole house is rented for one by written arrangement, and no visitors beyond the guests on the booking. San Diego water and energy limits mean the dishwasher and washing machine run before 3 pm or after 9 pm. There are cameras on the outside of the house in public areas, none in the back yard.
