This place is amazing. Anthony has created a unique, comfortable, intriguing, special place and is letting us all have a chance to experience it. Me and my girlfriend stayed here for 3 weeks in August and didn't want to leave when the time came.
The location is awesome...the neighborhood itself, Golden Hill, is quiet, pretty and clean. It has direct access to Balboa Park and wonderful views. If you go north you'll hit South Park, a really cool, hip neighborhood with restaurant and bar options. Even further and you'll hit North Park, which is a more developed commercial part of town with lots of stuff to do. Both of these are within 10 minutes driving. The beaches are also super close because Anthony is right next to the freeway. Just hop on and you can get to OB or Coronado in 15 minutes or less. Even spots like La Jolla and Pacific Beach are within 20 minutes. (We had good luck driving in the afternoons to Ray's Rentals at Mission Beach and grabbing surfboards or paddle boards for an hour or two...from walking out the front door to getting in the water was 30 minutes max).
The treehouse itself was perfect for me and my girlfriend. It got tons of sunlight, and wonderful air flow. We were working remotely while staying here and the wifi connection was reliable and fast. We both found comfortable spots to set up shop and get down to work. The kitchen has everything you need, the shower is incredible (dual shower heads and a large tub), and the bed was comfortable. Waking up to a rising sun out one window and the SD skyline out the other is hard to beat. The one caveat is if you're sensitive to noise from airplanes, they fly over this neighborhood as they approach the airport.
I love how the treehouse seems designed for readers. For one, there are books everywhere. Secondly, there are so many awesome spots to read. Whether it's on the deck, in the nook in the front (my favorite spot), on the couch, upstairs in bed, or in the loft on the futon, you have a remarkable selection of places to really get into whatever you're reading.
Lastly, Anthony is a great host who is both helpful and understanding. We will be sure to stay here again next time we're in SD.
