When we arrived to appartment, nobody was waiting for us, but instruction how to get in and rules about the flat were clear. Appartment was very big and bright, everything works. Neighbourhood is very good, 10 minutes walking to train station and bus to Etna, a lot of shops, restaurants.
P.S. The houseceepers wrote that it takes about 1,5 houres to get to the airport on AliBus, but we got there in 25 min. You just need sit down in the bus not near train statiun, but catch it near Istanbul cafe. Becouse after train station the bus going to the city centre and after Istanbul cafe he drives straight to the airport.
