Ahmet's place was perfect. It's as described - the perfect studio within walking distance to the famous Istiklal street.
Pros:
- very walkable to the train station
- easy to get to everything
- place is big enough for two people
- Ahmet was very responsive and even left an IstanbulKart (metro card) on request
Just a note:
- it's a bit of an uphill walk to Istiklal street. The first day it seemed really intense but your legs get used to it really quickly. Istanbul has hills in general so it was no big deal.
Overall, it was a great experience and I would totally recommend this place to any one considering it.
