Location is absolutely amazing — Taksim, ferries, Galata etc — 10 min walking distance! The communication was great, Begun met us at the apartment and even gave a list of cool places to visit.
Accommodation is quite bigger than on photos, especially a living room. Lots of sun is there the whole day long.
Wifi speed is 88 mbps, but there is almost no connection in the bedroom where the working table is located (8 mbps).
A/C is old so in the summer it is super hot even if the conditioning is on.
The teapot is kinda broken so we used a pot once to make a hot water for tea.
There are washing machine, dishwasher, huge wardrobe (it is a separate room), balcony — bigger than on photos. Looks like perfect flat for a long stay. Plus the location makes it even more perfect!
