For the Geo Quiz we're looking for a very cool hotel that stands out from the crowd. This European hotel is located near a city square called the Plaza de Callao. It's got a view of the main thoroughfare called the Gran Via. So we want you to name the city that's home to the Save the Beach Hotel.

It's a hip spot alright but it didn't make the newest list of the world's trendiest hotels. The TripAdvisor website posted a list based on input from a random group of savvy travelers.

And they say the trendiest hotel anywhere is CitizenM in Amsterdam. This hotel boasts: �we are young and we are cool.� Art Series hotel near Melbourne, Australia came in for high praise for its great vibe and great service. And Hotel Missoni in Edinburgh Scotland ranks among the trendiest�it's described as magical and luxurious.

But if five star accommodation is not your style or in your price range then check out the Save The Beach Hotel. It's a new hotel in the Spanish capital Madrid, the answer to our quiz.

The new hotel there is generating some buzz, not for its five spacious double rooms but because its been decorated with trash, and it's free if you win a lottery to stay there. We're not talking any old trash, but twelve tons of of garbage that's been collected from beaches in Spain, Italy, France and Belgium.

Don't worry says a guest staying at the hotel: �I felt great there because it is not the kind of trash that smells or feels bad. You sleep on a normal bed�.

Its German designer says Save the Beach Hotel is an eye-catching way to highlight the tons of garbage that washes up on beaches. HA Schult says he's trying to make politicians and policymakers more aware of the trashing of beaches:

�The political people must hear us because the world is changing so fast, and garbage is a path to show us where we are, and the oceans are the biggest garbage dump of the world�.

The anti ocean dumping message is echoed by another of hotel's designers Fernando Godoy: �Suppose someone goes to the beach and tosses 3 or 4 cigarette butts and a can of Coke. Now multiply that by 47 million Spaniards, or by 300 million Europeans, or by 6 and a half billion people in the world. That where it's taking us. So, yes, it is a good thing to make people aware of beach litter�.

The Save The Beach Hotel isn't going to be around long. It was built to coincide with a tourism trade show in Madrid and it closes next week.

The hotel will be dismantled but the artist didn't say what he plans to do with all the leftover garbage.
