Good location, although Teksim (or what's left of it) is a fair hoof from here. The studio is functional, i.e., it has everything on a miniscule scale. I never met Efe who had either lost his phone or it was out of power. I was given both versions of the story. This caused a lot of problems. I kept texting him at that number as agreed with him without success. Finally in desperation I turned roaming (extremely expensive) on on my US phone and got an email from his partner, Mahmet. Mehmet came to meet me with the key. The room wasn't ready. The sheets were unchanged, full ashtrays and miscellaneous stuff lying about. Mehmat would never respond to text messages. Perhaps he didn't want to text a US number. I would text him no reply. After waiting I'd call him and then he'd answer the phone. This was expensive (roaming charges) and annoying.
