The apartment's really good. Has everything you need for a convenient life.
The bathroom has a washer and a dryer which is brilliant (no need to dry your clothes for a long time).
Really comfortable bed and very quiet.
There's also a working desk and good internet, so if you need to work remotely, it's a good option for you.
Great surroundings: park and coast for walking and running.
Marmaray and buses are a 5 min walk which is great (you can achieve any place in the city w/out big problems).
The host is really responsive and helpful.
