We had a great time at Kristen's cottage. Ocean Beach is a perfect place to stay in San Diego - very relaxed, close to the sea and amenities, but a real community feel too. The Cottage is well appointed, and we felt perfectly at home. As others have said, there is a bit of aircraft noise, but this didn't really affect us, and it was very quiet apart from that - given the jet lag issue coming from the UK, we slept pretty well!
