Booked a standard room to stay as close as possible to Anaheim Covention Center. Just 200 meters form the Center and 500 meters from Disneyland Resort. The building itself is well maintained, but you can see the time passed since its openinig. Rooms are remodelled, with all necessary equipment. One major dissapointment was the entrance door to the room. Absolutely no noise isolated. Zero. I couldn't sleep because of either other guests passing by my room talking or the constant, horrible noice of the icemaking machince just 5 meters from my room. TOTAL FAIL! How can you instal a noisy equipment that close to a guest room?!
A la carte breakfast is not the best choice either.
If you're looking for a peaceful stay, go to Sheraton Garden Grove hotel.
