Mixed feelings for this accommodation. While it is located fairly conveniently near Taksim Square, Istiklal Street, and the metro station, this place, like many guesthouses around, is located in an area with narrow streets making car pick ups and drop offs (eg, to and from airport) a little inconvenient. Walking to the hotel also involves a hilly stretch- to be borne in mind if you have elderly in your travel party.
Staff at front desk were professional, responded to requests quickly. There was ni room service provided in the 4 nights we stayed, though place is generally clean. Some amenities were broken - large cracks in toilet bowl, hairdryer would always go off halfway. And the worst part about room 102 which we booked was that it was adjacent to the reception desk and staff toilet, meaning every interaction and use of toilet could be heard loud and clear in the room - the be considered if you are a light sleeper or don't like noise.
No breakfast offered but a lot of eateries in the area offering breakfast.
