I spent a very pleasant week in Istanbul in Kerim's cozy apartment, very well located a stone's throw from the Osmanbey metro in Şişli, which is an excellent starting point to visit the main sights of Istanbul (by metro 30 minutes from Fatih/Aya Sofya - Vezneciler station, then tramway -, 20 minutes from Eminönü - Haliç station - and by bus 15 min from Beşiktaş/Dolmabahçe from where you can go to Asia, and only 15 minutes walk from Taksim square).
The apartment : new, spacious and of high standard, impeccable cleanliness and maintenance, well air-conditioned and soundproof, walk-in shower, comfortable bed mattress and fluffy sofa, modern equipped kitchen. The wifi connection is very fast and constant. It is also very convenient to have a washing machine inside.
Location : on a busy shopping avenue where all facilities are present: traditional lokantas, restaurants & fast foods, juice bar, pharmacy, currency exchange offices, 24/7 grocery stores "tekel" and Carrefour, clothing stores, laundries, shoemakers... the advantage of the Şişli neighborhood is that it allows you to immerse yourself more in the daily life of the Turks, as it is less touristy and noisy than Fatih & Taksim for example.
Service : the very friendly apartment worker always answered present from the handing over of the keys until my departure. He was very attentive, gave me many advices and good plans to make my stay even more pleasant, around several glasses of tea! A big thank you to him!
I will gladly come back to Kerim's apartment, who aims very high to satisfy his guests, and I highly recommend him!
