Jan was... perfect. We got in contact with a VERY short notice (the day before) and he was very helpful, quick to reply and willing to sacrifice even his own time to help us move to his place.
The room was big, with fridge, television, wifi... and much space to store your possessions.
Underground is 15 minutes by walk with a very nice neighborhood towards Turnpike station.
We had very nice chats with Jan and he also offered us dinner, breakfast, etc... all the times he could.

I would recommend to anyone with no hesitation.
