I loved my stay at Thomas' place. There was air conditioning at a time when Paris' heat wave was beginning. It's also right across the street from the metro which was excellent for those times I was coming back after dark and tired. The washer/dryer combo was super helpful as, with the heat, everything I wore got mega disgusting.
Check-in was wonderful. Patrick showed me all over the apartment and how to use everything. There was also some fruit and water which was great for the weary hot traveller.
The only thing I was to make sure I note for people is that you do have to climb down into the bath/shower. It wasn't a big deal for me, but if you've got bad knees or something, it might be a deal-breaker.
Would definitely recommend this place.
