We stayed at Sapphire, Beyoglu for 5 nights. Hatice was our host and she was extremely helpful and welcoming and guided us and responded to any questions we had. The apt. was very clean and the view is outstanding. It was a very convenient location to stay at, the main street in Beyoglu called Istiklal Caddesi, which is very lively and has many restaurants and stores was walking distance. The bus stop and Taxi's were easy to catch and the subway is walking distance as well. If I have to give Hactice any suggestions it would be that she could offer a faster internet connection. Also the apt. was on the 6th floor and has no elevator so it might be a challenge for some senior citizens. Overall we had a wonderful stay.
