Great apartment that was a joy to stay in. In a very central location in Beyoğlu with quick access to routes into main tourist area. Down a quiet side road, which despite the steep hill was a lovely location (those with disabilities might find it a difficult location to stay due to flight of stairs up to apartment and steepness of hill from apartment up to main road).
Berna is quick to provide any information you need and is clear with when you to check in and out. Also offered to facilitate a car to pick up from the airport which was nice.
Apartment is modern and clean with a nice big shower and beautiful terrace to relax in.
Would highly recommend to any travellers.
