Great apartment in a very comfortable location near the underground, lots of shops and department stores (Zara, Ka De We, etc.) and Berlin Zoo. Spacious 2 bedroom flat with 2 bathrooms (one shower, one bath) and fully equipped kitchen. The flat is part of the Sana Hotel, and so, there is a 24-hour reception, spacious lobby and a restaurant that serves breakfast for 24 € per person. The flat is cleaned and the towels are replaced every day. The personnel is very polite and helpful. They even left chocolates outside our door on Christmas day. There are radiators in every room for winter and central air conditioning for summer. Highly recommended!!!
