I had a wonderful host in Chillout Cengo Hostel. The Hostel is a house in city centre of Istambul, in Taxim Square, one of the best central points in the city; buses to the airports depart from here and is just 1 minute walking from Hostel. Everything is so close to the hostel, we can find tourist places as well as more local stuff. The staff in the hostel were the best, always abailable to help us, and so kind. Best guys to have a coffee or a beer in the way of our trip. Athposhere was great.
Would be quite better if you give some towells to the bathrooms.
The internet connecction was bad for who has not own laptop. There was just a public computer with really expensive prices to use it.
