Ace Hotel – When Ace Hotel opened in 1999, it was one of the first brands to appeal to the "creative class". Ace prides itself on its unique amenities, such as in-room turntables and locally sourced artwork and furniture. There are seven locations worldwide, with more in the wings.
CitizenM – In order to appeal to today's travelers, it's imperative to have high-speed wi-fi, and it better be free. Dutch brand CitizenM offers this, as well as artfully designed room (another important factor for globetrotting millennials) at a low price point.
Aloft – Like many contemporary-minded hotels, the Aloft brand has put a heavy emphasis on its communal spaces. The lobbies (dubbed the re:mix Lounge) are often outfitted with pool tables, board games, LCD screens, and various other features aimed at getting guests mingling. It was also recently announced that guests can use their mobile phone both to check-in, and in place of a room key. There are currently 80 Alofts in operation, with another 20 planned.
Andaz – Andaz is a Hyatt brand, which means guests can earn loyalty points. It's presented like a boutique hotel, however, with a strong emphasis on design. Often, local artists are tapped to give the space an authentic feel (Dutch Marcel Wanders, for instance, helped outfit the Amsterdam hotel).
Radisson Red – Radisson Red, which is slated to have its first opening next year, is striving to make its guest rooms feel like mini-studios, eschewing more irrelevant furnishings, like a traditional desk and one-person armchair, with more communal offerings -- such as a sofa and four-person table.
HTL Hotels – Stockholm-based chain Scandic Hotels is opening up a new brand this May directed at the next generation of traveler. HTL Hotels will offer small but comfortable, high-tech rooms. Guests can plug their personal devices into the LED TVs and play their own movies and music.
Moxy – Next year, Marriott will introduce their newest hotel brand, Moxy, which is aimed at the millennials. Though budget, the hotel will provide high-end bathroom amenities from Rituals. The lobby will feature lots of open spaces, and a video wall where guests can share their Instagram pics.
