Objective review:
Pros(+)
+We didn't meet Emeric but we had all instructions we needed and he was very helpful and fast responding to our questions.
+Good location, 5-10 min to Pantheon, 5-10 to metro, supermarkets,quiet place, elevator, 6th floor.
+Quite spacious flat. Not too big but not too small either.
+Shower and other equip is inside flat, just the toilet is outside, but there was absolutely no problem with that.
+Fast wifi in the flat.
+Very small balcony(Stand or sit for one person) if there is a need for it.

Cons(-)
-Flat is overcrowded with owners stuff.(Very different from pictures)
-When we arrived the flat was not very prepared. The flat was for 2 people but looked like it was prepared for 1. We had to take and extra half hour to clean the flat: vacuum carpet, throw away food leftovers from the fridge, clean tables, clean sink and shower out of hair...
-There was only 1 tea cup for 2 people. There was only 1 plate for 2 people. No sharp kitchen knife for slicing.
-Not comfortable to eat in the flat, becouse of huge school table with chairs attached to it and no where to move it
-Very small bed even for 2 skinny people to sleep

Verdict:
5/10
Flat by itself and its location is nice, but the equipment and preparation of the flat is not that nice and not comfortable.
Altought it didn't ruined or messed up the vacation it was fine and possible to live in.

Thank you
