Manhattan, particularly Lower Manhattan, is in the midst of a massive hotel boom. Over 18,000 rooms have been added since 2010, the New York Post reported. There are at least another 36,000 rooms coming and 12,600 of those are already under construction.

In Lower Manhattan alone, 6,300 rooms have been added since 2010, a 28 percent increase. There are 26 new hotels planned or under construction, representing 10,700 more rooms.

Some of the new hotels downtown are the 50-story Holiday Inn Manhattan-Financial District, which opened in 2014 and is the tallest Holiday Inn in the world with 492 rooms.

There are also a few new hotels on the Lower East Side, including the 50-room Orchard Street Hotel and the 293-room Hotel Indigo.

Coming downtown later this year is the Q&A Residential Hotel, a 132-room property. 140-suite AKA Wall Street will also be an extended-stay property.

Other new hotels downtown include the 36-room Riff Hotel Downtown, the 287-room The Beekman, and the 185-room Four Seasons Hotel New York Downtown.

A bit uptown, the 122-room Paul Hotel has opened in NoMad.

Another hotel is coming to the NoMad/Midtown South area. It doesn't have a publicised name, but is a 40-story, 164-room Rafael Viñoly-designed development from Flag Luxury Properties.

The hotel boom isn't limited to Manhattan. The 194-room 1 Hotel Brooklyn Bridge at Brooklyn Bridge Park and a 76-room boutique hotel called Gowanus Inn & Yard has been planned in Gowanus.
