Derin's apartment is a beautiful and spotless top floor flat in the heart of Beyoglu. It's a great place to stay for restaurants, bars, design shops, galleries, atmosphere, and good transport links to the rest of Istanbul! We found the location really useful for dinner, but also had a good time relaxing in the flat. One tip - if you are the sort of person to go to bed early, you might want to bring earplugs. The flat is in a buzzy location which is great for your trip, but it can get a bit loud! Derin was a great host too, she checked in and made sure we had everything we needed. Would definitely recommend.
