Cliff is an extremely nice, helpful and polite person.
The little home is as pictured: very clean, very comfy bed and space to relax in the evening; the little kitchenette was a +++ for us since we needed to cook at least once a day (US food is too strong for our stomachs).
The neighborhood is super calm, no noises, no people bruises, nothing.
What about Ocean Beach? We found everything we needed, from an ice-cream in the afternoon to a good margarita at night!
We rented a car, the must-see places in San Diego were max 20 min. by car from home.

We really recommend Cliff's place!
