Quite frankly everything was perfect and more.
Mehmet is a FANTASTIC host, the best I have ever met. Apart from being a great host he is a wonderful person too. He ensured and managed the process of arrival and leaving, by managing taxis, providing directions, communicating to drivers and a ton of other things, he has also been extremely helpful during our stay. He went over and beyond to make sure me and my family are looked after and welcome. Very responsive, he accommodated and assisted with every enquiry we had, what a great person he is, difficult to describe in words. If anything Mehmet has been a highlight of my trip to Istanbul.
In regards to the House, location is OUTSTANDING. Everything is at a door step, however away from the noise, basically all you need in Istanbul is just around the corner: sights, transport, restaurants & cafes. The house feels like brand new, very well looked after and has got this great authentic feel to it. Spread over a couple of floors with 2 community areas and a wonderful terrace. It has got everything you need and more. Apart from all the commodities that you get is a great value for money. Could not have picked a better place to stay at and what a pleasure to have such a great host. HIGHLY HIGHLY recommend.
