We enjoyed our stay a lot. Dimi's friend, who showed us the flat, was very friendly and "pro".
The flat is very well located, nice area : a little bit noisy at night but very charming with shops just downstairs and a park nearby. The metro is at 5-7 minute walk.
The flat in itself is tiny but it counterbalanced by the terrace, which is the highlight of the flat : big, in the shade, with plants, and a nice view.
The only downside was the bed and pillows, not super confortable but it doesn't keep us to recommend the place.
