We had very nice stay in Artur's apartment.
It is well equipped (air conditioning, coffe machine, microwave, etc.), very well located (1 min from bakery, 3 min to subway and 20 min walk to Eiffle Tower) and hosted by friendly guy. (very effective communication).
The only minus is 5th floor without elevator, but doing it once a day it is not a big deal :)
Strongly reccomend !
