The apartment is perfect. Very clean, comfortable and it has air conditioning in both bedrooms. Sofia is very kind and helpful. If you have a questions she answers immediately. She also provided lots of travel tips.
The location had its pros and cons.
It was very central, (very short) walking distance to the old city and all restaurants, bars etc. But it was also located in one of the busiest areas of Chania, so it's not a quiet place at all. There's a lot of noise from the streets, also at night. You definitely need earplugs to sleep here.
