Gris Verde apartment was a great stay! Akif is very friendly and super responsive! He was always available and provided me with the information I needed about Local transportation and popular sites to visit. The check in was very quick and easy and I was personally greeted by Akif and his wife. The apartment is SUPER secure. There is a code to get into the building that is changed every few days and you need an access card to get in to your respective room! The apartment is on the Asian side so to get to many of Istanbul’s main attractions you have to take the train however transportation was very simple. It’s maybe a 10-15 min taxi (30lira) to Bostanci train station and from there you catch a train to European side and arrive in maybe 15 min! Overall awesome stay the cleanliness and hospitality was unmatched! Would definitely stay again!
