Hotels are places that provide accommodation and other services to people who want a place to stay temporarily. These places have different services and charge accordingly. They range from a small bed and breakfast to posh hotels which have facilities like spa, swimming pool and so on. Hotels are of different kinds and some of these stand out due to their unique features.
Some hotels are constructed by using trees. These are generally for nature lovers and are often found in sanctuaries. A very good example of the tree house hotel is the Costa Rica Tree House which is located in Gandoca-Manzanillo Wildlife Refuge in Costa Rica. Some of them are transformed into one from a nuclear bunker. The Null Stern Hotel in Teufen in Appenzellerland in Switzerland is example of such a hotel. Some of them were made in caves. They generally have rooms under the ground which is built using modern technologies. From outside it mostly looks like entering a cave. Example of such cave places are The Cuevas Pedro Antonio de Alarcón in Guadix in Spain.
There is also something called a capsule hotel. This is generally found in Japan. In these hotels people sleep in the same room in different stacks. There are hotels that are made of ice. These hotels generally melt a little during the summer and spring season and are built again. The Ice Hotel in Jukkasjärvi in Sweden is a very good example of an ice hotel. Garden Hotels are hotels which are known due to their extraordinarily beautiful gardens. These make a very picturesque hotel. Gravetye Manor is one that is known for its breathtaking rose garden.
Due to the modern technologies people have also come up with underwater hotels. These have rooms which are under the water and people can see the water life all around them.
