We have had a very pleasant staying in Karim's apartment. He recieved us late at night and showed us everything in his apart: Internet, metro tips, stores nearby etc. He is a very reachable guy and gave us with his WhatsApp contact 24x7 in case we need. He also gave us his sister contact in any case.
Now, about the apartment: everything is as described in the pictures. You have a lot of windows to see a nice view to St Martin canal. There is a TV cable and a nice portable speaker that you can sync your smartphone and listen to some music. Bed is very comfortable and soft. The only thing I missed is a better refrigerator (I like to drink a very cold beer, which is impossible in a mini bar frig).
In overall, there is nothing to complaint about the place nor the host. If you want to stay in a nice place, clean, cozy and with a nice view, you will not regret staying in Karim's apartment.
