Pelin was a great host, gave us useful tips on the neighbourhood (and the location of the best baklava shop :)) on our arrival and kindly booked a taxi for us for the airport.
The flat is as in the photos. It is in a very central location in Beyoglu. Lots of cafes / bars / restaurants are situated in the vicinity, the nearest Carrefour supermarket is about 5 mins away. We used the tram a lot to get to Sultanahmat and the ferry to the Asian side, departing from Karakoy. The nearest tram stop is about 10 mins away downhill - definitely easier to walk down than to climb back up!
