We loved staying at Maciej's place! It's beautifully furnished and decorated; it looks even better in real life than it does in the photos. The bed and sofa are both super comfy. It's close to two Metro lines (one is about twenty seconds away from the front door, the other is a couple of minutes down the road). We could get anywhere we wanted to get to around Paris within 20 minutes. There is a great patisserie down the road, and a few cool bars within five minute's walk. Communication with Maciej was very easy. We did not contact him throughout our stay, but he was punctual with check-in/check-out, and offered us lots of good advise :-)
