One thing I would say about this place is that the overall feel of living here is wonderful and perfect for tourists. The location is 5 star, very busy with great shops and restaurants just as you step out of the door. Very good vibe overall. The beds were comfy and the building has been kept in retro style which is a nice touch. Washrooms were a little small, and one shower didn't work properly but that was not an issue for us. Hot water was available at all times. Some useful kitchen amenities were also available.
Please note that the rooftop is 5 floor of stairs so not very practical to go all the time but a good view nevertheless. Also, the streets around are very steep (and very beautiful) so be ready to do all the walking. We did have some issues with taxis as the place was accessible after going into small streets so many taxis would struggle to find the way if they weren't using maps.
As for Akif, he was a wonderful host. Responded quick to all queries, check-in and check-out were smooth. And he also recommended some places before our arrival. I would definitely recommend this place.
