Host did not meet us - immediately before we were to check in he said he was on vacation. Cleaning lady gave us key, but language barrier prevented communication. WiFi almost nonexistent unless you stand in hallway or go to café. Internet is VERY important when you need translations, directions and maps, or to communicate with host. Location is great, appliances are good but you must speak German.
I could overlook the little imperfections, but not having internet access, especially when advertised, is crucial. I'm sure it works in his flat, but the walls are very thick and did not work in ours.
We loved the neighborhood, the shops and Paris, but I would prefer someone who is available. I wonder how far in advance he knew he would be on vacation before letting us know right before we arrived.
