I already live in Istanbul, my family came to visit me so we rented the space for a month; here are the pros and cons of my experience:

Pros:
- The flat was great, accurately described, clean, spacious and well furnished with everything that you might need.
- The location is amazing, literally next to Galata Tower Square with easy access to restaurants, bars and public transportations.
- Deniz the house manager was great and helpful, she explained everything and was very welcoming.
- They were kind to let me have a tour of the place before booking it on the website (since I live in Istanbul).

Cons:
- The flat is in the fifth floor with no elevator, the view is worth it but it was a bit hard for my mom and dad to climb the stairs daily, it is a bit noisy as well but normal due to the central location.
- During the middle of our stay the internet stopped (due to over-usage which could have been from the previous guests), we were asked to pay extra to recharge it at first or wait a couple of days till the new month starts but after speaking with Deniz and Nadira and explaining that my 65 year old parents rarely use the internet they resolved the issue with no extra payments.
- The place is beautiful and it's normal to have rules however we were reminded many times of them which made my family feel a bit less comfortable.

Overall my family was pretty happy of their stay, Deniz and Nadira are professionals and are reached easily when needed. I wish you guys the best!
