First of all - very friendly, polite and hospitality host and was always in touch!
Apartment was new, pretty clean and tidy. All you need for 2-3 person comfortable visit for short-length staying.
Amazing view from apartment & unforgettable view from observation deck at 32 floor in the same building (free entrance 24/7)
You also had everything you need (and a little bit more) for your trip near by: carrefour supermarket at entrance, restaurant with simply food at 1 floor (meat plate highly recommended) and free public swimming pool!
10-15 minutes by foot to Yenisahra metro station
