If you’re looking for a truly affordable hotel in Europe that doesn’t involve surly front staff, decor from the 70s, walking up 10 flights of stairs, or a PC from the 90s that qualifies as the “business center”, then you should check out Generator.

This hip hybrid brand of hostel and hotel rooms has opened properties in Barcelona, Dublin, Copenhagen, Venice and Berlin, all at seriously reasonable prices with shared rooms as low as 15 Euros. Even their two newest properties in the world’s most expensive cities–London and Paris–are still wildly affordable thanks to a new 20 percent off promotion.

Generator London (near King’s Cross) and Generator Paris (in the 10th Arrondissement) have 24-lounge, cafes and nightlife venues. And of course, there is free WiFi here.

To book, select your dates and check the “Pay Now and Save” option. Rates for the private rooms in London were going for 53GBP in mid-June, while private rooms in Paris were at 67 Euros.
