This is a nice, cosy apartment just a few minutes' walk from Taksim square, the metro station as well as the airport express (havatas) stop. Perfect space for two, it comes with a well-equipped kitchen, clean albeit small private toilet and a spacious bedroom. Air conditioning is strong - a bonus during the sweltering summer.
The host was great, very responsive to messages and he allowed us to check in early as ours was an early flight. There's a receptionist 24/7 so anytime you need help there's always someone there.
Only slight complaint was the wifi, which isn't strong in the room. It worked fine for the first few hours but then fizzled off. We had to go down to the lobby to get a stronger connection.
Overall still a great place, very value for money and we still certainly be staying there again.
