Found an article in a Romanian newspaper (link at the end of the post for those that know Romanian) with a top 10 strangest hotels, and I thought of giving more details (and pics) about that.
10. Wild Canopy Reserve located in Masinagudi, Tamilnadu, India. Strange as it may seem but these are tree houses. "If you’d rather admire the fauna from afar, we can always see to it that your rooms are higher than an elephant’s eye – forty-one feet high, to be exact. We offer tree house accommodation with well-appointed toilets- running hot and cold water, out of reach, but with a clear view of the animals that congregate around the watering hole below."
9. Benesse House in Kagawa, Japan. This is more a museum than a hotel, since you find well crafted art all over the place. "Benesse House is an art museum combined with lodging facilities designed by the renowned architect Tadao Ando, and features permanent exhibitions of site-specific artworks that can only be viewed in this unique setting".
8. Exploranter, Overland Hotel in Sao Paulo, Brazil. As the name suggests, this hotel expores stuff. Mainly because it's on wheels. Kind of a modest one (with around 28 beds), is more suitable for people on the move (just like sleeping on a ride). "It is a mobile hotel, fully equipped with industrial kitchen, hot showers, 30 leather seats, 28 beds and lots of mobility."
7. Kasbah Du Toubkal in Marrakech, Marocco. "The Kasbah du Toubkal, just 60km from Marrakech, situated at the foot of Jbel Toubkal - the highest peak in N.Africa. A Berber hospitality centre (hotel/auberge) for groups and individuals. Stay for a few hours or a week!" Don't book this one if you're afraid of heights.
6. Woodpecker Hotel, in Sweden. Why woodpecker? Well because it's one of the smallest in the world, with lodging facilities for one person or a couple. Oh, and it's on a tree.
5. Whitepod in Switzerland. Well this is situated at 5577 feet in the Alpes. And it has 5 modern igloos. "Whitepod is not just another hotel. It's unique and ecological. Distinctive pods, pitched around a chalet, offer unprecedented accommodation. Far from crowds, yet with the highest standard of style, comfort and service, Whitepod offers an unforgettable mountain experience. Simply unique. Absolutely exclusive."
4. Jules Undersea Lodge in Key Largo, Florida. This one is underwater. "For the first time in history an authentic underwater research habitat is open to the average person--sport divers and even those who have never before dived. And although Jules' still functions as a research lab, you will be pleased to know that it has air-conditioning, hot showers, stereo music, VCR/DVD, a fully stocked galley, and unlimited diving for certified divers!"
3. Gamirasu Cave Hotel in Urgup, Turkey. A cave that was transformed in a hotel. "The hotel is located in a restored thousand-year-old Byzantine monastic retreat which offers modern conveniences without distracting from the spiritual feeling of the area which has been known to be inhabited for more than five thousand years. Gamirasu cave Hotel is featured in major international travel guides as one of the best cave hotels of Cappadocia. It is also mentioned as a romantic escape for honeymoons in wedding magazines. The hotel has a total of eighteen rooms: nine standard double, four deluxe rooms, two Cave Suites, two Family Suites and one Deluxe Suite."
2. Propeller Island City Lodge in Berlin, Germany. Propeller Island is unique because in it each room is different: one might have a suspended bed, another room designed as a large tube and nevertheless the one where you sleep in coffins. "In both coffins you can even slumber beneath closed lids! Exclusively connoisseur room for all those "Nosferatus" who cannot wait for that which awaits us all. Whosoever has second thoughts can creep to the bedplace below, safe within the labyrinth. Not only a unique experience for Gothic die-hards...an exquisite location on top of that!"
1. And finally, the winner. Puerta America Hotel in Madrid, Spain. This hotel is famous because each of its floors was designed by a different famous artist. This is how Nouvel, for instance, had the idea to make a pool with black water, while Arad made one with tubular walls. "An idea of freedom come true, a gathering space merging different cultures and ways of interpreting architecture and design. A masterpiece that awakens guests’ senses, that breaks the mould by using diff erent colours, materials and shapes. A building that ushers guests into innovative spaces, a bold departure from the usual. In short, a hotel that is unique."
Now don't ask me about prices. Like one, go see the price tag. And make sure you get an inssurance, you never know. And here's the Romanian article.
