I went to this hotel having read the positive reviews here on Trip Advisor. Now I realize that these reviews are quite old, and perhaps the quality had dropped over the years.
I went for work in Ouagadougou and the internet was disastrous. They have six different wifi networks you can sign onto, and most did not work. Most time was spent shifting from one to another in a vain effort to find one that worked for even a few minutes. Thus it was not feasible to work online at the hotel.
The air conditioner in my room and my colleague's room barely cooled our rooms at all. At midnight when I woke up in a heavy sweat I realized that if I turned on the overhead fan that made the room more tolerable. The rooms we had were clean, but small and very minimal.
I had just arrived from the US was jetlagged and needed to sleep. I ordered dinner at the hotel. I got a dish with chicken that was so hard and rubbery that could not cut it with my knife or pull it apart with my hands. I only was able to get meat off by digging my teeth into it, and there was little meat. Restaurant staff were kind, however.
We had reservations for five nights (again based on reading positive reviews). When we told the front desk manager that basic things we needed to do our work did not function (internet and CA), we were told by the primary reception staff person that we would have to pay the full bill for all nights we had reserved for. The discussion became a difficult argument with him the night of our arrival and then the next morning. Eventually he involved his supervisor, and after sitting with him and his supervisor, the supervisor negotiated with his own staffperson (!) that we be allowed to leave after paying the bill only for the one night we had spent. This wasted at least an hour of our time and created frustration and anger during the 15 hours we were there. A night reception manager was much more understanding, but appeared to have no influence on decisions.
I've worked in the region for 2 1/2 years and now visit frequently for work, so I am somewhat accustomed to the region, hotels, facilities and food. My experience at this hotel was worse than my experience in many other places in Burkina Faso, West Africa and sub-Saharan Africa. We had wanted a nice change from the larger, impersonal Splendid Hotel, but the decision to try the Palmeraie was a mistake. We then returned to the Splendid, which, while not perfect, was significantly better. Most basic things do function at the Splendid.
