I was in Istanbul for an extended business trip, along with my partner and our lady cat.
Even though the house had some minor shortcomings to support our long stay at first, the host made every attempt to accommodate us and make us feel at home. You can expect a hospitable host and a welcoming experience from him.
The pool, the gym, and the building in general is very well maintained, which we enjoyed a lot. The area is also very nice and safe. Water Garden is a nice spot to have a meal and start your day.
