Built in 2009, the Adina Apartment Hotel is situated in a seven-story building with a gray facade accented in white window trim. A standard but pleasant white-tiled lobby is made stylish by a roomy sitting area that feels like a living room. A large brown-and-orange Greek key rug sits in front of a fireplace surrounded by library-like shelving lined with rows of books, pictures, and curiosities, while gray couches and cup-shaped armchairs provide seating. The bar offers another nice lounge spot with velvety, button-tufted wingback chairs and squat leather armchairs finished with nailhead trim. Art in hallways gives off a subtle geo-tribal vibe. The hotel's apartment-style rooms tend to attract traveling families and couples, especially those staying several days, but the hotel is also host to business guests, in part because of its convenience to Central Station. 

The apartments are located in a pretty area of Berlin's central Mitte borough, between a small park and a medical university, just a two-minute walk to Berlin's Natural History Museum. There aren't a ton of places to go out in the immediate neighborhood, although a few restaurants and a coffee shop are on the same street. Plenty is accessible on foot and via public transport, including the Berlin Wall Memorial, the Reichstag, and the Brandenburg Gate. For sights further out, the hotel is just a one-minute walk from the Invalidenpark transit stop, which is host to trams and buses including the TXL bus to the airport. The Naturkundemuseum U-Bahn Station and Berlin Central Station (Berlin Hauptbahnhof) are also within a short walk. Parking is available on-site, but it costs an extra fee.

The Adina Hotel features modern, clean, and amenity-packed apartments available as studios as well as one-, two-, and three-bedroom units. Decor is subdued but tasteful, with a palette of brown, gray, and white. Striped throw pillows, leathery square ottomans, and bright white Eames molded chairs add modern style. Walls are finished with framed botanical pictures that are a nice accompaniment to the decor. Bedrooms in the apartments can be a tight squeeze, but the common areas tend to be roomy. 

All rooms include individually controlled air-conditioning, safes, tables and seating areas, work desks, irons and ironing boards, iPod docks, and flat-screen TVs, and most include washers and dryers. In-room Wi-Fi costs an extra fee, however. All units also have kitchenettes, most fully equipped with amenities such as medium-size fridges, microwaves, two-burner ceramic stovetops, sinks, toasters, electric kettles, and dishwashers, along with plenty of dishes, glasses, cookware, mugs, and utensils. Rooms are stocked with a small number of snacks and alcoholic and non-alcoholic drinks, which cost an extra fee. While guests are provided with dishwashing detergent for the kitchen, those who wish to do laundry should bring their own detergent, or they can purchase it through the hotel. 

Modern bathrooms are fully tiled in brown and white and may include a shower or a shower/tub combo, along with a toilet, sink, and the laundry units. Bathrooms are stocked with Naturals toiletries and an in-shower body wash dispenser as well as a magnifying mirror and hairdryer. 

The Adina Apartment Hotel offers a fair amount of on-site features, but most are attached to extra fees. The hotel's casual on-site restaurant serves up breakfast, lunch, and dinner, but these all cost an extra fee -- though guests do rave about the wide selection and quality of the breakfast buffet. The bar has a nice lounge area and offers daily happy hour deals. Room service is available during limited hours, and grocery delivery can also be arranged. Health facilities include a fitness room that's small but well-equipped with modern cardio and weight machines as well as a full rack of free weights. The hotel also has a sauna and a small indoor pool surrounded by a few loungers, though it can get a little crowded. Guests can order in-room spa services. The hotel also has a small terrace with seating, three meeting rooms, and a computer for guest use. Wi-Fi is free in the lobby and restaurant -- but only for 30 minutes -- while in-room Wi-Fi incurs an extra fee. The hotel has a 24-hour front desk, and staff can help arrange babysitting, car rentals, dry cleaning, etc. Up to two pets are allowed per apartment, though they are an extra charge. Other extras, like additional beds or cribs, also incur fees. On-site parking is available for an extra charge.
