Berna made us feel like we have a close friend in Istanbul. She recommended excellent restaurants, gave us shopping tips and also came to our rescue when we briefly lost our passports in a cab! (our bad)
The apartment was spotlessly clean and tastefully done with all the essentials of home (dish washer, hair dryer, nail polish remover!) and all the latest amenities.
The location was very central, safe and peaceful.
The one thing was, guests should know that the flat is on the top floor, and if they're bringing a lot of luggage they should have the muscle to lug it up. The buildings in the European side of Istanbul, are very old (and renovated) and most don't have elevators.
