The Tree House checked off every box we wanted for our stay: close to everything, private, and comfortable. Having the crib set up was perfect; my 2 year old daughter immediately identified it as her bed and slept soundly every night, which isn't common for her when traveling. We especially enjoyed the patio and the garden area. Aside from a few distant sounds at night, it didn't feel like we were in the middle of Long Beach.
The space was generally pretty good for the kids to hang out. Having the beach toys there was very useful. The house was very clean and well-stocked. A full-sized washer and dryer made it easy to pack light and do a little laundry during our stay.
My wife and I said on several occasions during the week that if we lived in Long Beach this would be a great apartment to stay in long term. We will definitely check on the availability of this place next time we visit. Thanks!
