Great host and great apartment! There are 2 bedrooms, a living room, a kitchen and a bathroom. Everything was clean. The apartment is also very stylish and well-equipped. Wi-Fi works well. There are some groceries in the street and a Starbucks in 5 min walk. Taksim is about 15 min walk but you need to go downhill and then uphill again, so please note that if you have heavy bags.
Jayne was very helpful, she helped me to check-in on a later date (as my flight on the original date was cancelled). The stay was very pleasant overall, many thanks!
