A fantastic experience with a fantastic host. The location is terrific and if you wish to walk then you can walk down to sultanahmet in around 20-25 depending on your pace but you can get the tram from right more or less right outside the accommodation and that takes around 7-10 minutes. Regarding the immediate area around the flat, it's great. Lots of places have breakfast, dinner or shop should you wish to do so. We strolled around until gone 1am and it was still bustling and a really great atmosphere. Most of all what made our trip great was Basma, such a wonderful host who made us feel welcome immediately. The flat was cosy, clean and well equipped. Only regret is we didn't spend enough time with Basma due to us spending all day round the city, but would highly recommend staying with Basma if you decide to go to Istanbul.
