Positive
========
They have a great service , super nice staff who can speak English (trust me this is a big thing in Istanbul) they are all friendly and available all the time .
The location is really close to Taqsim square it is like 2 mins walking distance and there is a supermarket around the corner.
Good prices considering what you get for it.
Negative
========
If you are a person who is sensitive regarding how clean the place should be and expecting that it should be as clean as 5 stars hotel is then this place is not for you. If you look for dirty spots you can find them.
although the location is really close to Taksim square but the street itself is not so pleasant. Many beggars, and prostitutes can be spotted.
Overall
======
If you look for a decent place to stay that is safe and close to everything and with great staff who can help you with your staying, then this is a place for you .
However if you are looking for luxury of services and you are planning to spend a lot of time in the hotel then this is not the place for you and better to find more expensive place for that .
