I absolutely loved my stay in SMARTments Prenzlauer-Berg. The studio was clean, had many new and handy appliances (toaster, microwave, dishwasher!, coffee machine), enough storage space, a big, clean and well-maintained bathroom and a great bed. There is even a storage room on the floor where you can pick up and use appliances such as an iron, a vacuum cleaner, a drying frame for your laundry (there is a laundry area on the ground floor) and extra cleaning materials. The service was superb, staff was very friendly and helpful and after service hours there is a night guard or a phone number you can dial in case of an emergency. I stayed at the studio for 8 nights as I was participating in a conference and it provided a quiet, clean and wonderful home away from home, with a supermarket, drugstore, an S-bahn and U-bahn stop literally 2 steps away from the building. Bikes can be rented in the Vienna house at the Andel Hotel, just around the corner. I definitely recommend this place to people travelling to Berlin.
