We had a wonderful stay in Bilgé's lovely apartment. Her mother let us in and the whole process was very smooth.
Although not in the centre of town, transport to the apartment was very quick and regular, and the location had lovely views out over the lake, and was 5 minutes from a large supermarket and other shops.
The flat itself is just as lovely as it looks in the pictures and is full of books about art and design. We stayed with our 18 month old and wouldn't recommend it for a child of that age - too many nice ornaments and books to try to destroy! - but for an adult couple it would be ideal.
Overall we had a wonderful stay and would definitely recommend this place to others.
