"This apartment's exposed brick and plaster walls, concrete design elements, and plants galore give the space a modern feel, while 70s-style wire chairs and fabrics bring their own retro vibe. Take note: the listing is a private room (with its own bedroom and bathroom) that shares a common rooftop, outdoor living room, and kitchen with another Airbnb listing, so consider it best for solo travelers looking to make friends. (You can book both if you have a large enough group.) Book Now: $41 per night, airbnb.com" - Meredith Carey
