The location of the flat is excellent as it's less than a minute walk from the metro station and also very close to Taksim and Galata Tower. The host is also amazingly kind and always available and the flat is clean, with adequate amenities and a great view from the loft.
The place is good for two people but it's quite cramped. It's also important to note that it's on the fourth floor and the spiral staircase is tiny so getting up and down can be difficult.
Overall I would recommend this place if your priority is proximity and access.
