People usually build apps on top of the Twitter service, but heard of a (physical) hotel that's built by using Twitter as a theme? Its exists for real.
Sol Wave House, a hotel on the Majorca island town of Magaluf is an entirely a Twitter-theme based hotel.
Guests can login into a custom-built app that will enable fellow customers to tweet others staying in the hotel, share pictures, send private messages to guests, tweet a service request to the concierge.
The custom app can be accessed only via the hotel's wifi network, in a bid by the property to create a virtual community for guests to share information and pictures.
A few of the items inside the room are serviced via Twitter.
For example: The hotel has placed a "#FillMyFridge" sticker on the in-room unit to encourage users to tweet using the hashtag if they need to refill their mini-bar.
Apart from various other type of rooms in the hotel, there is a room known as the "Twitter Party Suite" (picture below).
Also, another sticker "#AskMe700" is placed in rooms encouraging users to use this hashtag when asking for any help of the concierge team.

The Twitter focus is extended to services outside the hotel room as well. For example, each of the Bali beds in the pool have a number and guests can simply tweet with the Bali bed's number (#BaliBed5) to request for any service.
Gimmick or otherwise, similar to the Ushuaia Beach Hotel on the fellow Balearic island of Ibiza, interesting to note the extent in which travel brands will go to in order to differentiate themselves from the competition in busy markets (like Mediterranean beach resorts) by tapping into a wider social trend (such as Twitter).
