Dimitra's apartment is very sweet and cosy indeed, its in a very central location (close to the Louvre) yet Herold street and the blocks around it are very quite. we were worried about the place being on the fifth floor with no elevator but it turned out to be very easy to climb with the steps being pretty small, and the way up is a lovely prissian old style architecture.
But the best thing about staying at Dimitra's is Dimitra herself. not having met her in person or even speaking on the phone, Dimitra was very attentive and replied honestly and quickly to any request or question we had about the place before booking and while we stayed.
Me and my partner made a mistake and didn't book our last night in Paris online, since Dimitra already had other guest booked we couldn't stay at her place. however, she immediately responded to my emails and found us another place to stay for the night. we felt very much taken care of, and that is a very important feeling to have while visiting a foreign country.
We will defiantly recommend Dimitra and her place, and on our next visit we hope to come back and stay there as well.
