Can't recommend this place highly enough, stayed in places with more stars not nearly as good as this little gem. Everything from quick response on email before arriving to super easy check-out.
When arriving at the airport you can take bus no. 60 to Santa Catalina bus station (blue Global buses). It leaves 15 min past the hour, cost EUR2.95 one way and takes about 30min.
Hotel is about 15min walk from the bus station.
Upon arrival I was please to check in an hour early but even more to find I'd been upgraded to a Superior Suite :) There's a lift in the building if in need.
The Suite itself was very clean and comfortable, the kitchen had all the required amenities even a little treat box with a few tea bags, chocolates, water etc. Lovely bathroom with a proper hair dryer, not one of those little flimsy ones you find attached to the wall in many 4* hotels.
I'm a light sleeper but found the bed to be very comfortable. Regarding noise, I found the windows blocked quite a lot of when closed, the aircon was fairly quiet (didn't keep me awake) and yes, you can hear the neighbours but only if they are inconsiderate and slamming doors/loud music which I was lucky enough to escape.
Round the corner from the beach, plenty of supermarkets, shops and restaurants especially loved Taberna Chica for their delicious fish and steak dishes.
I'd never stay anywhere else if ever in Las Palmas again :)
