We have really enjoyed our stay.
The location was great, perfect for young people as lots of cool bars and cafes are walking distance. This makes it a bit noisy in the night, so keep that in mind if you are a sensitive sleeper, but for us it was totally fine because nothing can be noisier than Istanbul.
The apartment was clean and cozy, it had a cute balcony and everything you need for your stay.
The check in was easy and independent, the instructions are clear, and host is always in touch to help you resolve the problems.
Highly recommend!
