This is one of the best places to stay at by far. If your not familiar with Turkey and Istanbul I recommend this place.
It is near the train station that goes directly to the main city center areas. You can easily purchase an Istanbul card and go to city for a couple of cents. You are also nearby the ferry boats that go into many directions. There is a mall with literally anything and everything that you need. There is a food market downstairs for all your needs and much more.
The convenience of the location is amazing. There is also a Starbucks nearby with many more restaurants and shops.
The balcony is huge and has stunning views. The kitchen is stocked with utensils. There is a washer and drier for convenience. Literally better than staying at a hotel. If you are looking for a family friendly or even solo trip location this is definitely the place to stay at.
