Staying at Chuck and Helen's place was wonderful! It's located only a few minutes walk from the beach, right in the heart of the Ocean Beach neighborhood. Chuck gave us a tour of the area when we arrived and had lots of great recommendations for activities and restaurants. We had the whole guest house and hot tub to ourselves but Chuck was close by if we needed help with anything. Chuck and Helen go above and beyond in hosting; they even had a bottle of wine and snacks waiting when we arrived!
I would definitely recommend staying with them if you are planning a trip to San Diego.
