I booked a 3 night stay during the local holiday season in Al Qubbah Al Thahabiah via a 50% flash sale on Hotels.com at only 75 SAR per night, and it was definitely worth the price. The double room we were given was spacious and generally clean with the home-like décor giving it a relaxing feel. The bed was very comfortable, and the Wifi connection was good too. Location is also very convenient with local amenities and food options being available in close walking distance, while most famous attractions in the city are just a relatively short drive away which the hotel driver (Mohammad) provides cheap rates for.
Although the hotel is in need of a 'face-lift' with the lobby area in particular feeling quite empty and bare and some items of furniture visibly outdated and in need of replacing, the overall experience was positive and I recommend this hotel as a good cheap option for a quick city getaway.
