The place was good, with great location and comfortable to accommodate 4 people. The host was responsive which facilitated our arrival. The only issue is the security. Although, thankfully, we weren’t affected by it, the door locks are based on codes, which seem to follow the same pattern for the different room, so I can imagine it is easier to guess the other rooms’ security passwords. Thus the room seems vulnerable to other people’s entrance. But as I said, we had no issues personally so I can only be happy with my choice of accommodation in Istanbul.
