I stayed at this place for 5 nights. It's on the first floor of the apartment. The area can be a bit noisy at night because of the neighbors around, but it's at a great location, a 5-10 minutes walk from Taksim Square and Istiklal Street, Metro Station, pubs, and restaurants.
Overall, the stay was great, I had comfortable 5 nights in the room. It's perfect for one person and has excellent value for money.
