I spent 4 days (3 nights) at Arjens apartment in Istanbul with my girlfriend. Arjen was there to welcome us and show us the apartment even if we was 15-20 min late. He had a big smile and the good will to explain everything and answer toour questions.
The apartment was just like the photos, perfectly clean and exactly what you need for a short stay in Istanbul. When you open the door is the kitchen and the redecorated bathroom. You go down the stairs and you will find a comfortable double bed and enough space to leave your staff. The hole space is not huge but is enough for two persons.
The apartment's location is perfect. 3-5 min from Sishane Metro station and Tophane Tram station. That makes it perfect to move whenever you like. Just where Sishane is, the Istiklal road starts who is full of stores restaurants and cages and leads to Taksim square. Galata toweris just 5-7 min walk and the hole neighbour has an alternative-hipster atmosphere with a lot of cafes and shops in that mood.
We loved our stay at Arjen's Airbnb and I definitely recomend it if you want to be in the heart of Istanbul for a few nights.
P.S. Arjen's apartment is not suitable for disabled people because the neighbour has a lot of stairs and climbs and the apartment has a round stair to go downstairsto the bedroom.
