There is a distinct lack of info/reviews of this hotel since it is so new, I would love to hear about your experience once you are done.
We had some ups and downs with this hotel due to their construction delays, which are still continuing, but once we actually arrived we had a wonderful stay. Way back in March we made two reservations -- one for May that was cancelled with less than two weeks' notice because they weren't open yet (luckily I'd made a back up reservation) and one for this past weekend for a two-bedroom suite for my daughter's birthday trip with her best friend. Last Wednesday they called to say the two-bedroom suites were still not finished, so they were moving us to two connecting studio rooms instead, but they further discounted our stay and only charged us for one studio room (so we ended up paying $325 total with tax for two nights in two rooms). Samantha is the one who called and worked with me and she was there and greeted us on arrival. All of the personnel we dealt with were friendly and helpful. They provide late checkout (1 pm) free of charge if capacity permits, which was great for us to run to the park early on our last day and then come back around noon to do our final packing and rest a bit.
The rooms were spacious, clean, and new and great for an extended stay with a fully-equipped kitchenette -- full-size refrigerator, dishwasher, plates, silverware, knives, dish soap, dishwasher detergent, real creamer for coffee/tea, paper towels, etc. You could save a ton on food by packing picnic lunches or eating back at the hotel during breaks. There is a roll out table so it's easy to eat in the room as well. Large TV, comfortable couches and beds.
Bathroom was great, good shower water pressure, shower head high enough that you don't have to duck under, provided 6 towels as standard (we stay at so many hotels with a 4 or 6 person occupancy that only provide 2 or 3 towels). I did find it surprising that they furnished mini toiletries instead of reusable wall-mounted dispensers.
The breakfast was the standard Home2 Suites set up (based on our experience in other locations) and was perfect for grab and go if you wanted to eat on the way to the park or in line -- they have three different types of hot breakfast sandwiches, bagels and bread, yogurts, boxed milks, coffee/tea, two different juices and two different "enhanced waters" in dispensers. They also have two waffle makers with lots of toppings (chocolate and caramel syrup for instance) and oatmeal with a variety of toppings, plus four cereals.
The pool and spray ground are still a work in progress, so if you want to swim you have to go to the adjacent hotel.
Our rooms looked out toward
Disneyland and we had a view of the Matterhorn (many of the rooms would look out on either the Fairfield Inn or toward I-5, so if you want a park view, request a high-floor room in the northwest corner).
Despite the slightly longer walk, I would 100% stay here over all of the "crosswalk" motels on Harbor if the price were comparable or even $40-50 more per night, especially for a 4 or 5 day stay where the breakfast and nicer accommodations are more important. However, when I priced them for our next two weekend visits (in February and April), the prices are significantly higher, so we're sticking to the Fairfield Inn for our February trip and Desert Inn and Suites for April.
