The hosting was very good, no problems at all. Tansel loan us a valid Istanbulcard: a very nice idea indeed: its very usefull and saves s lot of time. Than he loan us also a activated turky mobile phone, so we could contact him amytime without the enourmous roaming costs. Also pretty good idea. Also the location is perfect. If you plan a trip to Istanbul with 2, 3 or 4 people, please consider Tansel.
