Theo was highly helpful from the beginning. He answered very quick to my request and the booking went smoothly well.
I didn't meet him coz busy at the time we arrived, but I met her mom, a bright and cheerful lady.
Apartment was tidy and clean. A bit cold but it got warm as soon as the heaters were switched on.
Something important is that apartment is located in an old building and lift gets to 7th floor, then there's narrow stairs to the 8th. Bear that in mind if you have big or heavy luggages! Otherwise apartment is perfect, neighborhood is super nice (there's a very good restaurant just below), good connection to the center of Paris.
In all cases, we really enjoyed staying at Theo's, he was really kind, we would stay here again!
