Great Location. Right near Taksim Square and Taksim Metro train station and around 8 mins walk to the bus stop for Airport. 5 mins walk to Istiklal Street, which is full of shops and restaurants and leads to the Blue Mosque, etc. which is a 25 min walk away.
The hotel itself was Ok. You need to check in at the main hotel, Endless Suites, which is just a 2 mins walk. This is also where you have your breakfast. Breakfast was Ok, but they don't refill stuff towards the end. Checkout was easier. I just had to leave the key in the room I was staying in and shut the door. No need to walk back to the main hotel.
The room was clean and a decent size for me as I was on my own. Rooms were made up and fresh towels laid out everyday. But although the bed was made up everyday, they did not change the sheets for the 4 nights that I stayed there. The grout in the shower was a bit grotty and could do with a clean.
To sum up, I quite enjoyed my 4 nights there and would stay again.
