This place is good in general, although the building itself is quite old. The host himself is helpful and gives some instructions. The room I stayed was decent enough and usually quiet which allowed me to work from home during my stay. Cleanliness in general could be better. Heating system was not very good. This can be greater problem if you visit during cold months. Location of the place is very good, since you can easily walk central places (Taksim, Istiklal) and then continue with public transportation.
