I stayed at the Gran Luna in July for a conference. The location was pretty bad considering how much you pay for it. The only thing within walking distance is a K-mart style department store. The rooms were standard but bad for business travelers hoping to use laptops, etc. The reception staff was horrible and unwilling to help. There are many tour groups that stay here, so you will be competing for attention. The restaurant buffet breakfast was disgusting, and the dining room messy and dusty. At night, hordes of teenagers would gather across the street and play loud music, and race their cars around the surrounding streets, so between that and the highway noise, good luck getting a good night's sleep. Better off staying in the Albaicin, city center, or if attending a convention, stay at the Hotel Saray.

We found this through the Octopus website. The hotel was £47 per double room per night and our expectations were low. In fact, the hotel was clean comfortable and with all the amenities you might expect from a 4 star hotel (including a swimming pool with towels provided). I am unsure as to whether the previous reviewer was unlucky in his choice of room or whether there has been a re-fit ince then but the rooms were clean, everything worked and we had no complaints. Even the included breakfast was varied and edible.
The hotel is a little way from the centre (about a 10 minute walk but no joke in the summer heat) but there is a huge El Corte ingles next door for shoppers and the public transport connections are good. Finally, it is extremely easy to get to by either car or air, being jus off the ring road.
The only negative point I would make is that it is used a lot by tour groups and the service is reasoanble but soulless

This hotel looks like it must have been very luxurious when it first opened, but it's not being maintained, and the waterfall near the elevator just seems silly at this point.

My room had nothing luxurious about it. The toilet made a loud whooshing sound once every two minutes during the entire two days of my stay, and the staff's method of "fixing" it was to flush it a couple of times and then tell me it should be fine, leaving quickly before the whooshing sound happened again.

There were dirty marks in the bathroom.

My colleague's room was perhaps worse than mine. His window wouldn't close properly, so he heard the highway during his stay, and the hair dryer fell to pieces.

I'm usually not that picky about hotels, but I just hated this one. I think it was even worse because I saw the 4 star rating and had high expectations.

I stayed in this hotel on January 26, 2005. Beautiful, comfortable hotel. I used Bancotel coupons. Only one coupon of 50 euros for one night. Clean, well appointed rooms. Not Bad! It is located just right. To go to Alhambra you will have to take a taxi or take the tourist bus .90 cents (euros) from the Cathedral which is probably a 10- 15 min walk. The staff at the hotel were very courteous and professional. They have a parking for 10.00 euros a day. A good choice if staying in Granada.
