Wanted to add some information as just completed many nights here:

Hotel is quite nice, and likely ranks #2 or #3 for hotels in Addis (#1 Sheraton, #2 /3 Radisson, a very distant #4 Hilton).

You will find many people working in the lobby every day as luxury hotels are one of the few places to get reliable wifi in Addis. The wifi had a 90% uptime while I stayed.

Rooms are modern, with plenty of USB and charging outlets, but not particularly spacious as the property is crammed onto a major intersection. Make sure to ask for a pool facing room as these are quieter and do not face the intersection/highway.

Please note that Ethiopia is extremely homophobic and checking into any hotel with two people of the same gender in the same room will always raise eyebrows. We were booked with two adults into a room with two separate beds and the check in agent said "you have two room reservations, right?". Extremely unprofessional but goes with the territory in Ethiopia and is the standard in all of Ethiopia; however I was hoping that a brand like Hyatt would not promulgate such behaviour, I was wrong. Most tourists visiting Ethiopia are unlikely to have a problem with this as the country attracts more than it's fair share of conservative Americans and Europeans.

As of this post only one restaurant with an Arabic/Mediterranean menu, and a cafe with a limited menu. Both are acceptable quality-wise for Addis, and priced reasonably (300 ETB for a pasta). However there is a much larger menu for room-service and pool-service, strangely, with many more options. A second restaurant is being opened in the coming months, as is the spa. The hotel is currently still in it's soft opening phase. Service is quite mixed; staff are probably 20% friendly and competent, 50% friendly and need more training, and 30% ambivalent and in need of training. For example, every room/pool service ordered was consistently assigned cutlery with the formula (# of patrons/entrees - 1 = # of cutlery sets). Room was not cleaned for three days despite three separate requests.

The pool is quite nice, though not cleaned adequately. Was able to write my name in the thin layer of green grime accumulating on the pool, despite daily (ineffectual) cleaning. Likely due to poor training, pool temperature kept comfortably warm, and inadequate chlorine. Would not advise young children swimming. Has poolside seating for approx 20 individuals, and can get busy on weekends from expats with memberships, with extra lounge seating for another 40 directly behind. Gym is very nice, spacious, and well appointed.

Hotel does not provide free airport transportation, unlike most hotels in Addis, which is a shame considering the extremely high room rate (200 USD per night), shuttle is $7 USD pp. Despite the high room rate you will find that most hotels in Addis provide extremely poor value in terms of hotel accommodation to the price compared to other destinations in Africa. However there is a serious lack of choice/competition until the Four Points (under construction) and other hotels are added in the next few years.
