Such a great place to stay!
My family and I stayed for couple days to celebrate New Years. The host send me all the instructions ahead of time so check in was easy peasy. The place is really close to Galate tower which is surrounded by cute little cafes and restaurants. And all other attractions are a short walk away.
I had a restful sleep every night which is always nice.
If I’m ever back to Istanbul I would definitely try to stay at the place again.
