I emailed back and forth with the Hostal and they were so nice. I actually ended up cancelling my booking.com reservation because you can geta cheaper rate directly through the hostal. They go out of their way to be helpful and are very nice at the hostal. They can book tickets for Al Hambra, which I highly recommend!! Why stand in line when you dont have to???
The location is great but it could be a con for some, it is right by the tapas area of town so there are tons of bustling cafes on both streets (the apartment is in between). We didn't mind because we are used to living in the city but I could see that for some people with small kids this may not be ideal. Otherwise the location is perfect for getting to both Al Hambra and the city center. It is very central which makes driving kind of a pain in the butt (which we knew going in). What we did is parked illegally while one waited in the car and the other ran to get the key for the parking garage (it is closeby but trick to get to), it costs 15 Euro.
Also the internet available is not wifi, so if you want to use it bring a cable.
