I had a great experience of staying in that place. After i booked it the same day in the morning, i requested about the time i may come, for which i have been given an answer immediately. It was very helpful.
The apartament is very clean and tidy, and i really felt like i own some piece of privacy 1 minute walking from Taksim square. And no doubt, the location of the place is 5-star which would give you the great flexibility for exploring the city either by walking or using the opportunities that public transport provides from this area.
