Everything went seamless, so we did not need to contact the host. The location is very good. Different supermarkets are 10-15 mins around by walking. Bus and train stations are just around by walking. One can reach the house by local trains (U-Bahn) in 10 mins from main train station (Hauptbahnhof) in München. Check-in was quite easy and straightforward. Although the house has no private parking, it was not difficult to find free street parking around. I thank Alex for being our host.
