Kai was a good and nice host. All of my emails were answered quickly and completely. Kai welcomed us into the home and told us about the place. The neighborhood is a little rough around the edges but it seemed safe.
Kai helped us understand the tube (there was a tube strike). The flat is near shops and a quick walk to the bus and a 10-minute walk to the subway stations.
But there is some bad. I hate to speak badly since Kai is such a great person but I need to be honest.
Nothing gigantic but these things added up after a few days. The front door is really difficult to lock from the outside and to unlock from the inside. That was very annoying and dangerous in my opinion. The wifi didn't work in my room--it sounds like a small deal but when traveling in a new city this is important to me.
The shower seal leaks so the floor or your clothes get wet. The toaster burns. The ironing board was broken. The pillows were old. There are other flats so you share dishes, garbage and fridge space with other people.
I would have liked to have seen the backyard but it was overgrown and full of old furniture.
So if you want a decent place run by a wonderful host for a great price and can overlook some of these things you should jump on in.
