We booked a one bedroom with a sofa bed (in a separate living area) for a family of four. We also had a kitchen. The place is huge! So much room to spread out. Our stay here was at the end of a two weeks trip and having some space to yourself is so nice when you're together 24/7. It's clean and well kept. Having read other reviews, I knew that the hotel did not have an elevator. We were on the third floor but this was not an issue since we travel light. While we were there, the weather was nice so we opened the windows. However, I don't believe there is air conditioning. Breakfast was the usual cold foods - yogurt, cereal, cold meats, bread and rolls. They also had eggs. FYI - the 147 bus stops not far from the hotel - a 1 minute walk. The 147 goes to the main train station (hauptbahnhof) as well as to Friedrichstr subway station. If you get off at the Friedrichstr Bhf bus stop and look across the street, you'll see the Rewe grocery store. (You'll want to use the bus if you're carrying groceries). There is also the TXL bus to the airport that you can catch at the Karlplatz stop. Super easy. The hotel is only a 10 or so minute walk to the Reichstag building. So convenient - I would absolutely stay here again.
