We have never met the host or anyone that work for him but, his istructions were realy easy and clear.
The appartment was as describe except the "double bed" that is actually two singles stuck together (unconfortable). The Wifi often didn't work well (often slow).
The location is realy pretty and confortable in a great quite zone, in front of a good bar for having breakfast, near (5 minutes walking) 3 different metro stops.
