Before traveling to Qatar, it's a good idea to find out the cost of accommodation in Doha. It all depends on your budget: if you prefer the best service, you'll naturally be priced accordingly.
It is important to consider one nuance: before chasing a big-name hotel, first study similar offers. So, for example, if the Grand Hyatt Doha hotel can charge up to 250 USD/night, for the same dates you can easily find another 5-star hotel where prices are much more democratic: within 150 USD/night..
