Serdar's apartment is very spacious with 2 living rooms and 2 balconies both with views of the Bosphorus. There is ample space for many people to stay and loads of kitchen supplies. The kitchen and bathroom are brand new. The apartment can be improved with better lighting and for those with sensitive back issues, the beds could be improved. The couches though are much more comfortable than one might suspect and can be used as beds also, once opened up. Serdar was very thoughtful and communicative. He checked on my arrival a week before I arrived, assisted with all my questions about the apartment and kept in touch throughout my month stay. The apartment is in a great neighborhood, very close to all transportation (except metro, which is a short bus ride away either to Osmanbey or Gayrettepe). Besiktas is a wonderful region also with a bustling marketplace, lots of restaurants, cafes, and bars. It is one of the most enjoyable and still authentic regions of Istanbul, which is also on the coast.
