We were met by the charming owner, Mustafa who was the epitome of clear and fast communication. The apartment is incredibly close to Aya Sofia, Topkapi, etc which makes it very easy for sightseeing & for easy walking to those within 5 minutes, then Beyoglu in 30 minutes, the Grand Bazaar in 15 minutes etc. A GREAT location. The apartment was spacious & airy with nice high ceilings & the heating made it cosey & warm in the winter weather. Our final highlight was watching dolphins in the Sea of Marmara from the window while it started to snow outside. Only reason not 5* is that the apartment is not ultra modern, (showers & bathrooms, though they are definitely adequate) however it is very clean and very acceptable in every respect. Mustafa is a gentleman & a good and very caring host who really will make sure you have a good holiday. We recommend.
