I know that FS Doha is essentially a business hotel, but it is also a very good leisure hotel. They have an incredible Spa, which makes this hotel a destination spa in its own right. They also do great BBQs on the beach a couple of times a week. The beach is decidedly swimmable, service is excellent and rooms and suites are very comfortable indeed. Food, too, is really good. I have stayed here around 3 times and always wish I had stayed longer.
