Ae's place is great! It's in a great location - walking distance to shops/restaurants, the zoo, public transit, etc. It was perfect for our little weekend getaway to San Diego. There was a little more noise than what we are used to (since we were not used to city noise), but I imagine this would be true about any place downtown.
Ae was extremely responsive, and was very accommodating about our late arrival to San Diego. Ae's an excellent host and we would definitely recommend this spot to others looking for a convenient place in San Diego!
