The room had the following problems so I could not sleep at all and then checked out after first night.
1. No AC or fan - if you can sleep with window open with street noise and sun light
2. No curtains - only net - so lots of sun light from early morning (was asked to see the pictures carefully - my understanding is that curtains are standard)
3. As no AC or fan very early morning construction work started with high noise
4. The hotel is on the middle of a very steep road so no matter what way you take - your legs will be tested - especially with luggage
5. Low quality bed - made noise when you move .
6. I checked out at 11 am next morning due to these problems and asked to part refund - was refused
7. Location is far away from Taksim Metro (the initial map before booking - I think shows nearer) .
Positive
- Good communicator after booking
- Self check in was good / even late night
- A small store is nearby
- Wi-Fi was good
