Some budget hotels, especially in Granada’s Albaicín area, run a “bait and switch” scheme. Guests are welcomed at a pretty location only to be told that their room is housed in a different, much less charming, building. These places do not issue receipts and do not have a complaints book, both of which are requirements to operate legally.
In the heat of the summer, it’s wise to be attentive to the freshness of what you consume. Tapas that look as though they’ve been around a day too long, anything to do with mayonnaise that’s been sitting out of the fridge and, of course, shellfish served in less than fastidiously hygienic establishments are probably best refused.
