Check-in is tricky as there is no reception and we only found the manager through the good graces of another guest or possibly an apartment dweller. Also, he is only available during stated hours - we were early (before 3 p.m.) and he would not answer his doorbell.
It's not a B&B in the British tradition - they don't provide a breakfast, though if there is a kitchen, you can make one yourself - they will provide some factory made croissants and Keurig-style coffee packets. Our Krups coffee-maker was on its last legs so you had to be patient when making coffee. There was a microwave that didn't work properly, a good fridge, a 4-burner gas stove with low heat (maybe it's normal in Spain), only 1 frying pan and 1 saucepan, plenty of plates and cups and flatware, not much cooking utensils - tricky to make any real meals. The kitchen space is very small - think ship's galley. There is no real dining room - we ate in our bedroom. Bedroom was fine, bathroom was very good with very modern shower stall.
