We were really lucky to come across Özge and Cihan's place, as our host from our previously booked flat in Istanbul had to cancel for medical reasons the day before we were due to arrive in Turkey. With less than 24 hours between the moment I booked and our arrival, the communication with Özge & Cihan was flawless and they messaged us regularly to make sure we had all the info we needed to come to the flat from the airport, advising us on several routes possible by public transport and taxi.
They welcomed us very warmly when we arrived (even though we were late), explained everything and they had a lot of added bonuses waiting for us in the flat like a guidebook of Turkey, a map of Istanbul, local tips handily sent in a Google Maps list, and even a little welcome gift! The ad mentioned free breakfast and indeed we had some great produce for us in the fridge : olives, cheese, bread, jam, eggs, tomato spread, etc. (Turkish breakfast spreads are the BEST!)
The flat itself is great and very accurately represented in pictures: cosy, comfy, well decorated and functional. It is also greatly located a few minutes from Taksim Square and the main shopping street Itsiklal, where there are a lot of restaurants as well.
All in all we had a great stay in Istanbul, the flat is great value for money, Özge and Cihan were great hosts that I'd recommend to anyone. As for us we will happily come back when we return!
