The hotel is located in a quiet area within easy walking distance of public transport (U2 and U6, busses, S-Bahn, taxis) and a short walk from Checkpoint Charlie. At check-in we were offered an upgrade on our reservation and treated to an incredible apartment with a nice balcony, separate bedroom with a great closet and flatscreen, and comfy beds, a large bathroom with washer and dryer (there's an iron and iron board as well), and a living area with a pull out sofa bed and second flatscreen, audio system, desk, a completely furnished kitchen and neat dining area. There is a Lidl (supermarket), several convenience stores and a fruit monger around the corner, so stacking the fridge for snacks and breakfast items is easy and convenient. The hotel has a swimming pool, sauna, gym and hot-tub with great facilities in the basement, with fantastic towel-service, and never too crowded to enjoy and relax after a long day of sight seeing. There is a nice inner courtyard, and the restaurant is decent in quality and price. The staff was very friendly (I was traveling with a noisy 7 year old) and highly professional. The safety box didn't work at arrival, and within two minutes of calling, there was a staff member at the door to fix it. Excellent housekeeping. We will stay at Adina next time for sure!
