I spent 5 nights in Sylvester's wonderland, he has a really big house so you can really have enough space. the atmosphere is very friendly and you can feel natural and as if you are realy at your own home.
Sylvester was very friendly, I had many questions, especially about transportation which is quiet complicated on Munich and he was very helpfull and even printed out for me the information.

So my advice to you is to come open minded and things would
be great.
