Yankel's place is great if you're looking for a great location... it is close to Les Halles, and has a Subway stop nearby.
On the downside, it is on a 5th floor And there is no elevator; something to keep in mind if you bring heavy luggage.
Yankel was a great host and was available by phone when I called him. We had a cleanness issue when we arrived but got solved within the hour.
I would recommend it if you value location over confort.
