Hakan's place is very well located, large apartment east to Kadikoy centre. The apartment is on the 3rd floor, so you'll have some exercises. You'll live in a nice area with grocery stores, parks and cafes available, and it's 30 minutes walk from the apartment to the beach.
The apartment definitely needs to be cleaned better and we've found ourselves with a lack of essential items in the kitchen. The furniture is really old, some items are broken and it all needs to be cleaned or replaced. The small room with a single bed has holes in the wall. The main bedroom is fine, the mattress was comfortable. The living room has a projector with the Netflix subscription available, you can also setup services like Apple TV+, YouTube or S Sport+ for football broadcasts. There's also 2 sofas, a chair and a table (good for remote work).
The communication with Hakan was fast, he told us about the delivery services and was friendly.
You can use Getir to order groceries or food, prices are reasonable and delivery is very fast.
As we're refugees from Ukraine, we had our plans changed at some point and needed to leave an apartment 2 weeks before the initial time. Hakan refused to refund us with the unused days or even to cancel the payment he didn't yet receive.
