Farouq was very helpful and answered any questions we had once we arrived at the apartment. The premises was very clean and tidy. The location has to be the best in my opinion, the neighbourhood is not loud at night and is very safe. There are countless restaurant and stores to get whatever you need. The Blue mosque and the Grand Bazaar are within walking distance. There are numerous tourist operators in the area within 2 to 5 minutes walking distance to book daily activities. There is a fantastic currency exchange facility across the road ahead (3 minute walk) with the best rates available. I would recommend you change currency there. I would also like to highlight that it's extremely easy getting a taxi on a daily basis from this location.
Overall the apartment is very clean, in a very safe and quiet (family friendly) location. Farouq is an exceptional host and recommend his apartment to anyone thinking of staying in Istanbul.
