I'll write in temporal order so I don't forget anything.
First contact were 8 months ago because host let you know if his flat is right for you. I never expected this and It's my first time. It's a plus. He gave also good tips on how reach his home from airport. He is a good, smart and great host!
When we arrived at train station from airport he went to greet us and to help to reach apartment.
Check-in and check-out are quick.
Home is nice with a good price/value. It isn't close to the centre but it has a good link with train and metro. All spaces are clean and Joek is very helpful with all our request.
One not obvious thing is a good quality mattress... it has ;-)
Last but not least there is a real italian illy coffee machine with 18 caps. GREAT! I couldn't wake up happy without a good coffee :-D
