Sebastian is one of the nicesest hosts ever. Very well in advance he makes sure you feel welcome and @ home in his house. Description how to get to his house very easily understandable.
I needed to change my flight and Sebastian was very flexible and able to let me check in early.
Since I was there for a conference we rarely saw each other - but Sebastian made sure I am alright and everything was ok and always offered his support.
The house is really close to a couple of different bus lines and you can easily reach the conference center by bus (takes about 20 min - 10 min walk, 10 min bus ride).
The room has a window to the backyard and is very quiet - which I really enjoyed after long days at the conference.
Strong recommendation.
