Guven's apartments are located in the very historic centre of Istanbul. Guven is a great host, always available and ready to help. Our apartments were on the 4th floor but it wasn't a problem despite us being a five year old child. The apartment is on a quiet street and is warm, which is important, since we came at winter. Thick, dark night curtains are available in both bedrooms. Hot water was always available.
We recommend this apartment to everyone.
Thank you Guven!
