I had a good experience overall. The staff was very friendly, and the owner was amazingly engaged in making sure that everyone was content and comfortable. You will be taken care of. If you meet the owner, ask for a quick version of his family's story - it's an amazing journey.
My room was large, clean, and well appointed. No complaints. There are a few rough edges, but on the other hand you get real warmth, not the sterile, anonymous comfort of a corporate place.
The attached Chinese restaurant is genuinely good - I'd patronize it in New York, and it's a real winner in Kumasi.
