I gave Erol and Emre's apartment 5 stars for a good reason. A number of reasons actually:
1. Location. This is probably the best location for an accommodation in Istanbul you can find. It is literally 1 minute away from metro entrance (Sishane station), 3-4 minutes away from Istiklal street and historical funicular. This means that you are within reach of many popular tourist destinations ether on foot or via transit without many changeovers. At the same time, the street where the apartment is located is quiet. So you get the benefit of being very close to everything, but not suffer from the noise of touristic areas. Hundreds of cafes nearby for every wallet.
2. Cleanliness. Apartment is very clean. Fresh linen and towels were there when we arrived (and can be changed at your request).
3. Communication. The best communication with an AirBnB host in my life. Emre was very helpful throughout the whole stay, and not just about the accommodation, but with other things a tourist may encounter.
4. Check-in. Very easy and simple.
5. Very reasonable cost. Probably the best value for money offer.
Overall, highly recommended! Will stay again when we come back to Istanbul.
