Stayed here with my sister and the location is unbeatable. You are steps from Galata Tower which is surrounded by restaurants and cafes. You are also a short walk to Taksim.
RE accommodations: washroom is small with 1 temperature faucet and modest shower. Bed was comfortable. Great windows looking over busy street (keep this in mind if noise bothers you, it was fine for us).
We felt it was a good value. Ideal if you are busy during day and need a place to rest at night.
