Peter is an excellent host. He was very responsive, provided breakfast and complimentary wine and beer, and was very respectful of our privacy. We also found the guest house very quiet, and convenient to both Balboa Park and restaurants.
There were, however, a few limitations of the guest house that prevent us from leaving a 5-star review. The main problem was the shower, which took a very long time for the water to warm up, and even after it did, was just barely adequate in terms of warmth. In fairness, Peter explained the delay in warming up was because San Diego requires low-flow fixtures, but whatever the reason, we were disappointed in the shower.
The closet was also just barely adequate. It was just a few inches deep - nowhere near the depth of a normal closet. We got by OK since we had only a 3 night stay and not many clothes to hang, but if you were staying for a week, it would not be adequate.
