The location is great, in a quiet lane behind main Sisli road - a 3 min walk up a slope and steps to the very convenient Harbiye bus stop and many cafes and minimarts and superstores. Sisli has good access to the main city area - taxis know it well, buses to Metro stations and everywhere. There is also a 24-hour small family minimart in the same street. It is a very safe and quiet lane. There is a street security guard cubicle right in front of Joy Suites' door.
The room is spacious and bright and airy, which is why we got it - just one small thing, because Joy Suites has several rooms, the picture u see might be a little different from the room u get. Mine was similar enough so we didnt mind. Though I did wish the plant in the picture was also in the room. The washroom is clean, spacious and user-friendly. Good bath area.
The kitchen corner is awesome if you like preparing small things - there are basic pots and pans, a frying pan, a deeper pot, a saucepan, 2 dining plates and bowls and cutlery and mugs. The room airs out very quickly too so smells and smoke dont get stuck in the room.
The daily cleaning service was great - quick and effective. Dilara was friendly and sweet and very good at cleaning. (On just one dayn the water used in mopping was smelling a little unfresh, but it cleared in 15 mins once we opened up all windows and doors.)
The receptionists were always available and approachable and helpful with answering questions.
It made our Istanbul stay very nice :)
