What a great apartment! The pictures were very accurate and the apartment was spotless. Good space for my group of 10. Two bathrooms was great and one of them is the largest I've seen in Berlin!
Very short bus ride to and from Tegel airport and the train station is only a couple minutes away and is on the Ring so transportation around the city was very easy as well. Restaurants and a grocery store within a few blocks walk make this a very convenient place to stay.
The staff was very friendly upon arrival and even let us check in early and have a nice storage space for luggage if you want to drop that off with them before your check in.
