When is a hostel not a hostel? When it’s a Generator. In 2018, after years serving young travellers looking for a cheap bunk and a good time, the brand formerly known as Generator Hostels trimmed off the second half of its name. At its Barcelona hostel-hotel, you can still get a bed in a shared dorm for prices as low as €20 a night, if that’s what you want. Or you can get a private hotel room with a king-size bed, en-suite bathroom, private terrace and view of the Sagrada Família, at a cost (starting from €86) significantly below what you’d pay elsewhere in the same neighbourhood.
