Selim is extremely hospitable and will contact you ahead of time to see if he can help you in any way. He did all our airport transfers and helped us with our luggage. The apartment is spacious with everything you could need for your stay, and is very conveniently located for exploring Taxim Square and Istanbul as it is close to public transport. Just note that Taxim is a historically significant neighbourhood and that the building is very old with old building problems such as smelly drains. It is predominantly a business district so there is a very active nightlife.
