The regular rooms are very dark - all rooms have a little less lighting anyway. These rooms have a window, but it faces the internal stairway, so there is never any natural light in the room .
Coffee should be complimentary.
Since the apart-hotel has a mini kitchen facility, if they provided basic Kitchen ware (1-2 pot/pan, spoons, forks, knives) it would be good.
Also - when one's on a holiday, room service would be great. If they can arrange for something even basic like croissants, juice or so, even if from a neighborhood cafe, it would be a convenient option.
Nevertheless - these are only suggestions.
We stayed in the regular room for 2 nights, and in the terrace room for 5 nights.
The facilities are perfect - good bed, clean, mini bar, great staff, elevator, sufficient space in the room.
The location is perfect - at the corner of Istiklal and Kumbaraci, 5 minute walk to the Tophane tram stop / Tunnel stop, Sishane metro stop, 15 minutes to Taksim.
The staff was extremely helpful - very warm and friendly.
The terrace room was just amazing - sitting out in the balcony, with a good view, lot of sunlight in the morning, spacious room.
Even the deluxe rooms are good, as there is a window facing the street so one gets good natural light.
We loved the place and would definitely recommend it to anyone.
