This room is located about 5 minutes away from the Grand Bazaar and the Tram (which is very useful), has good local amenities and nice clean rooms. They provide a regular cleaning service and rooms are bigger than average in Istanbul. It also has a nice Masjid across the road as well as a supermarket 2 minutes away which is very useful.
Points to bare in mind - For children, there are a few stairs to climb to get to the upper rooms so book one which is nearer to ground floor. Also there is an uphill trek to get to the tram which you do get used to.
Had the pleasant experience of engaging with Aiwaz who was the very helpful receptionist (all-round nice guy) at the desk along with Halil. Ultimately had a good experience and would recommend it to budding travellers to Istanbul as it is in a prime location and has helpful staff.
