Marcel's apartment is definitely great - very practical, clean, equipped but above all: IDEALLY LOCATED.
In the heart of Cihangir-Beyoglû, we were close to the lively neighborhoods and many cafes/supermarkets/boutiques and nightlife of Taksim and Karaköy. Below (count 5-10min down the hill stairs), we were also very close to a metro and ferry station which allowed us to go very quickly anywhere in the city (which is not so easy on the hills of Beyoglû).
Moreover, Marcel had a good communication with us and inquired several times about our satisfaction with the apartment. We had originally a bad experience arriving at a hotel in Galata, and Marcel proved to be very responsive and flexible in welcoming us to his accommodation and saving our stay in Istanbul!!! We recommend the apartment to anyone who is making a first stay there and will certainly come back here during future stays in the city!
Çok teşekkürler :))
