Communication was great not an issue there, he was excellent :) my issue really is that it is in fact a very noisy apartment, the bar that is downstairs is really noisy, and they go until very early in the morning 2:00am or more, we wanted to open the windows to let the breeze in, but the noise and the smoke was terrible.
I believe that the owner should invest in curtains, there is really no privacy for the people sleeping on the loft at all, nor for the people who is at the leaving room.
Very close to transportation, but we felt it was a bit far away from the things we wanted to see, for example, a taxi from Eiffel Tower was around 20min, and the cost was $25euro, something to think about :) unless of course you are good with taking the metro
