We stayed in this apartment for 6 days. First of all check-in was great. Volkan's coworker Velat was a kind person. Location of the apartment is near to the Istiqlal caddesi. It takes 15 minutes by foot to the Taksim square.
It is great for short term stays.
But there were some issues
1. Only 1 slippers was there but this apartment is meant for two people. Especially bathroom usually has slippery floor due to water. There should be at least 3 slippers at house.
2. The water heater (kombi) wasn't working properly. It was very hot. We had to consistently regulate it. To get cold water we had to turn off it completely.
3. There were no insect guards on windows. We were attacked by mosquitoes because some times we aired the apartment.
