The flat was nice an clean. Check in was very convenient. The flat is located only 7 min away from the main shopping street in Istanbul and close to the Galata tower where you have a good view over Istanbul. I can recommend the accomodation. I liked the fresh bread which you can buy accross the street and also the supermarket "Dia" which is also very close. At night it can be a little bit noisy. With earplugs this was no problem at all. Either Erdal or Seyma were always in the office to answer any questions. Seyma speeks perfect (!) German.

My advice: If you take the Havatas bus from the Airport to Taksim square I would recommend to take a taxi from there to reach the flat. Despite Taksim is only ca. 1,3 km away the walk to the flat is quite challenging (also due to a big construction site which you have to circumvent).
