We visited Monterey on a very busy weekend in August with our one year old. We had plans to visit the aquarium, and ended up going twice a day for two days. We live around her nap schedule, but the house was so amazingly close to the aquarium that we could make the <10 minute walk there with her. The location is pretty amazing with great views, and we ended up not using our car at all since everything, including the fantastic walking trail, was so close.
The house itself was the cleanest AirBnB I've stayed in. Was more or less exactly as promised, and Dean was very responsive when we had questions. We'll be back!
