We've rounded up our top ten romantic hotels 'with a twist.' Some may sound like heaven, some may sound like hell, but they're all guaranteed to stir up some hidden passion!

Hotel Chelsea - New York, USA
If you're after a bohemian atmosphere and bad behaviour, then this is the place for you. We're talking cool. Famous for its rock and roll reputation, Hotel Chelsea has been home to many gifted (and destructive) writers, musicians and artists, including Bob Dylan, Leonard Cohen and Jimi Hendrix. Hotel Chelsea is more than a hotel, it is a true New York institution.
Room Service Please: Hotel Chelsea, 222 W. 23rd Street, New York City, NY 10011, USA.
What's the damage? From £66 - £186 per night.

Ice Hotel - Sweden
Keen to try an unusual bedroom experience? Then try sleeping on an ice-block wrapped in reindeer skins. Sweden's Ice Hotel offers a unique opportunity to stay in an intriguing giant igloo - an unforgettable fairytale setting. If you think star-gazing is romantic, try going in search of the Northern Lights by snowmobile through Arctic forests. And where else can you indulge in a reindeer safari and husky sledge rides? Sweden is the ideal winter playground. Oh, and it's perfect for Vodka lovers too.
Room Service Please: Ice Hotel, 981 91 Jukkasjärvi, Sweden.
What's the damage? Doubles from £210 per night.

The Pavilion Hotel - London
Fancy a little OTT decadence? This glam-rock hotel is very popular in the fashion, media and music world. Rooms are themed to project funky and glamorous images and are crammed with quirky eccentricities. 'Casablanca Nights' for example, is a Moorish deco-inspired fantasy while 'Honky Tonky Afro' is a tribute to the 1970s - complete with disco ball, pink feather boas and lime green walls. Serious kitsch appeal.
Room Service Please: The Pavilion Hotel, 34-36 Sussex Gardens, Hyde Park, London W2, UK.
What's the damage? From £100 per night.

The Madonna Inn - California, USA
This place has to be seen to be believed. If it's 'wow' factor you're after (and that's 'wow' as in 'omigod') then look no further. Each of the 109 rooms in this Californian hotel is decorated with a special theme, from downright tacky to surprisingly imaginative. The Caveman room, for example, is a Flintstones-style cave made from real rock, complete with a 'waterfall' shower. If you're looking for something more luxurious, the Austrian suite is an elegant 76ft long haven with two balconies overlooking scenic San Luis Obispo.
Room Service Please: The Madonna Inn, 100 Madonna Road, San Luis Obispo, CA 93405.
What's the damage? From £78 - £175 per night.

Jules Undersea Lodge - Florida, USA
Perhaps namesake Jules Verne's idea of living underwater wasn't so crazy. The world's only underwater hotel is a dream come true for water babies and sci-fi fans. To enter the lodge, you have the unusual task of scuba diving through the tropical mangrove habitat of the Emerald Lagoon. Once there, rooms are fully equipped with hot showers / phones / TV's etc. However, the main focus is on the huge round windows that grace each room; waking up each morning at the bottom of the ocean amongst the world of marine life is something you'll never forget.
Room Service Please: Jules Undersea Lodge, Key Largo Undersea Park, 51 Shoreland Drive, Key Largo, Florida 33037, USA.
What's the damage? From £235 per person per night.
