If I have to compare, this hotel is really much better than let's say the Intercontinental. It is well maintained everywhere, the staff is very nice and professional and the restaurants are very very good and refined. When inside you completely forget about the bustling and polluted Addis.
The room we had was very nice and comfortable but as explain by some reviewers the A/C was not properly working and I am sure that it was much more than the 19°C mentioned hence some difficulty to sleep. Apparently they are on their way to fix this but that is why I will only give a 4 and not a 5.
As a general comment, it is also always annoying and "cheap" in a hotel that claims to be luxurious to pay an important price for the room and still have to pay some more few dollars for Internet access. Luxury is all inclusive for me (the not consistent part is that they offer a free shuttle to the airport).
