The realistic view
Beyond the first impression
Verified information onlyA 284-room, 27-floor business hotel opened in 2018 on Büyükdere Avenue in Istanbul's Maslak financial district, with the M2 metro (İTÜ-Ayazağa) at the door, an indoor pool, hammam and spa. Breakfast and parking are typically charged separately.
What it does well
- Business travelers working in the Maslak, Levent or Ayazağa office towers, reachable on foot or within one or two metro stops
- Anyone who wants to skip Istanbul traffic: the M2 line runs directly to Taksim without a change
- Project teams on multi-week stays; large rooms and the Executive Lounge make long stays workable
What to watch for
- Breakfast, parking, a EUR 100 deposit and a pricey minibar sit on top of the room rate; budget for the full cost.
- Explorers on foot: Sightseers who want to walk to Sultanahmet, Galata or Karaköy; the historic centre is 30+ minutes by taxi
- Business travellers: Anyone expecting street life in the evening; the surroundings are office towers with limited dining options nearby

Location
Istanbul, Sariyer
Maslak Mah., Büyükdere Cad. No:233, 34485 Sarıyer / İstanbul
Rail transit · 199 m
Istanbul Airport (IST) is about 29-33 km away, roughly 35-45 minutes without entering city traffic. Sabiha Gökçen (SAW) is about 33 km but usually 60-90 minutes because of the bridge crossing. Whether the hotel runs its own airport shuttle could not be confirmed; Havaist buses and the metro (M11 with a change to M2) are alternatives.
The hotel sits on the Maslak stretch of Büyükdere Avenue, opposite the İTÜ Ayazağa campus. İTÜ-Ayazağa station on the M2 metro is about 250 m away; Levent is three or four stops and Taksim roughly 20-25 minutes. Kanyon mall is about 5 km, and İstinye Park is a short drive with a free hotel shuttle running 11:00-21:30 (advance booking with the concierge required). Expect 30 minutes or more by taxi to Beyoğlu or the Beşiktaş waterfront depending on traffic, and 45-60 minutes by metro with one change to the old city. The immediate neighbourhood is office towers and the university; there are a handful of cafés and restaurants on the Maslak side but little evening life.
The stay
Editor's notes
Extra fees & things to know
A EUR 100 deposit for incidentals is taken at check-in on top of the room charge and refunded at check-out if unused, per the hotel's own reply on Tripadvisor. Breakfast, parking and spa treatments are billed separately, and minibar prices are steep. One guest reported a discrepancy between the website booking and the final invoice that could not be resolved remotely, so check the bill before leaving. Late check-out is subject to availability.
