Such a splendid stay. It costs about 60 Turkish Lira to take a taxi from the airport to Taksim Square. You can also take the metro to the funicular to Taksim Square. Once at Taksim, Oytun's place is a short walk away.
Oytun, Mehmet, and the rest of the staff speak English just fine. They served as my local experts from shops and dining to sightseeing and general getting around. Excellent concierges.
The room itself was like a small apartment, complete with stove and kitchen sink. The shower was fine, the toilet exceptional, and the bed was warm and comfortable. The wood flooring adds an unexpected element of class. WiFi is strong in the rooms. And the traditional Turkish breakfast was delightful and delicious.
My only regret was not staying longer. Excellent choice. Exceptional value for the money.
