It is located in a strategic area. You can walk in Balat with colorful buildings. You need to take one bus (around 10 min) & walk about 500 m to:
1. Galata Külesi
2. Sultanahmet areas
3. Taksim
But unfortunately the building isn't handicap friendly (no elevator and very tight & narrow stairs). It also hard for me to carry out my own luggage.
