This is a great flat, river side and roof top view. Berlin wall east side and metro station is in walking distance. My family had one very good week in the flat and in Berlin.
Ryan asked his friend to receive us in the flat, we wrote to his friend before we arrive, so we were being waited while we arrive, very smooth check in.
Only one issue is the parking. There are parking slots available, however Ryan didn't figure out which one is dedicated to him, but anwsered us "the parking slots aren't dedicated, so you can park any one in front of the building ", however, next morning, I went to check out my car, and I found a written warning letter. Later, Ryan advised me to park outside on the street, it is possible to find free parking, he said. I felt like, this advice is really not an useful one. Meanwhile Ryan was contacting his neighbor friend and tried to help me. Later, I met one of the neighbors in the parking slot, I was advised to park a place "normally free", and I wrote a message in my car with phone number on. But, nobody call me to move my car the next days. It was my first question to Ryan, unfortunately it was not verified clearly but in the end, no real issue happened. All in all, a good stay and happy experience.
