Pros:
-Karim went out of his way to meet us on the day we arrived. Prompt in responding to our messages.
-Great location, safe neighborhood, nice building, clean apartment
-Pullout couch/bed surprisingly comfortable
-Coffee & small kitchen appliances provided
-Close to metro, gym, Eiffel tower
Cons:
-Central heating in apartment building, not in unit. Since we stayed in December, we found the apartment to be a little chilly.
-Refrigerator was set up as a pay-as-you-eat mini bar, which left little room for guests' items.
-As other reviewers stated, this shower is tiny!

Overall, the pros definitely outweigh the cons. We were satisfied with our week long stay at Karim's place and would suggest it to others.
