This place is absolutely fantastic for a stay in Istanbul- situated right in the middle of the Taksim/ Beyoglu neighbourhoods with easy access to public transit.
Communication with the host was excellent- I faced long queues at passport control but Mert was happy to wait for me at the apartment and he was very friendly and welcoming when I checked in. He was also on hand via mobile at all times should I have any questions and he always responded quickly.
The apartment itself is well decorated, clean and there are two fantastic private outdoor spaces- a huge roof terrace with amazing views of the city and a smaller balcony that is perfect for eating. The bed was also comfortable and I slept well.
I had a great stay and will without a doubt stay here again the next time I visit Istanbul. Thank you Mert!
