Rana is a great host! Everything was awesome with our stay. It was very easy to communicate with both Rana and Cem, they are very helpful. We loved the apartment. The living room with all the retro stuff was a very nice place to have a rest after a walking day, it looks very cozy! There is a small balcony and we loved to sit with opened windows and talk during lunchtime. And the location is great with a lot of tasty and cozy cafes and restaurants around. Not far from ferries and from Taksim square. You can find some recommendations on the table when you arrive. Also my personal are Susam Cafe and Cafe 21. If you need a place with a good coffee that is laptop friendly you differently should go to 1 Coffee (1Kahve), it is very close to the apartments.
We stayed in the middle of September, so it wasn't hot in the rooms, but there is a fan if somebody needs it. The wifi connection and speed were good, it was necessary for me, so if someone also looking for a place with such requirements then Rana's place is a good catch.
