Simon's place is exactly what we needed. It is close to TXL, close to the hauptbahnhof, and close to all of the Berlin sights. The apartment is extremely spacious and very modern. Keyless entry is very helpful and makes for an easy check-in process. The beds are large and comfortable. We loved the balcony which was a very relaxing place to enjoy the nighttime breeze. If I had to give any constructive criticism, the refrigerators are a little small and you can hear the trains go by at night but neither detracted at all from our experience. I would highly recommend Simon's place to anyone traveling through Berlin and would definitely stay here again!
