Tycho's place is really nice and well situated for all amenities and the sights of Amsterdam. Tycho is efficient and helpful when asked and the room is well equipped. The towels that were made available were very small and the bed was sunken into the middle however.
He did text sms rather than send messages through the Airbnb app, which made things a bit difficult as we thought he was not responding (we were only accessing messages via wifi).
It is fair to say that the room needs a few minor repairs. There were some wires hanging out of the ceiling and there was no extraction vent in the shower - just a hole in the ceiling. The main problem however was the lead flashing at the top of the large window. This kept banging against the window all night due to the wind, and meant that we got no sleep at all on our second night. This meant we were extremely tired on our last day in Amsterdam, which was a real shame.
