Too noisy, dirty and too expensive
I stood one night at the Double Tree Hotel in San Diego and paid a bill of USD 325 for a room with view to airport and highway, a window that didn't close properly and let me enjoy all the noise from outside, cushion covers that were not properly washed, with smelly towels and a poor selection of soap and shampoo. The only positive point: my room was far away from the noisy ice machine. There are far better hotels in San Diego and I strongly recommend to avoid the Double Tree Hotel.
