Most relevant points have already been covered by other reviewers so just a few other things to add...

a) the picture of the lounge/dining room portrays the room to look larger than the actual size BUT the actual size was sufficient for us (a family of four) and exactly as shown in the photo in every other aspect. A very clean, tidy apartment and we loved the split-level style with a bathroom in the hall area and a good-sized, comfortable bedroom on the bottom level. Note that there is no washing machine in the apartment, however we did see a launderette close by.

b) Regarding the neighbourhood: yes, it does SEEM a bit seedy late at night due to the numerous groups of men playing cards outside local outlets and the somewhat dark streets but in fact the area is very safe. We came across several little girls playing on our doorstep in the evenings and the centrality of the location outweighs this potential issue.

c) Saban was an excellent host who was on call for us at any time. Great communication skills and I was particularly fond of his thoroughness in information provision prior to, during and after our stay. We felt we had a good balance between privacy and support. On the day of check-out, Saban allowed us to store our luggage in the communal hallway.

d) Internet connection was superb at all times. This is a serious plus. The tap water is perfectly safe to drink and this was highlighted to us upon arrival. Both air-cons in the living room and bedroom work perfectly but one remote requires replacement/change of battery.

e) BIM supermarket (cheapest in Turkey) is a three-minute walk. Another big plus. Taxi to Ataturk Airport cost us only 40 Lira, which we thought was very reasonable.

f) The sofa-bed is VERY comfortable - my sister and I slept on it two consecutive nights out of preference (the bed mattress is a close rival).

I think that covers everything. All in all, an apartment that we would book again in Istanbul as it is affordable, well-kept and very well located.

Thank you for having us.
