I warmly recommend Tassos' place!
It's clean, comfortable and in a good location (10-15 minutes from the apartment to the city center using the metro).
Tassos was keen to take care of my every need. During my stay I had a minor issue that needed fixing, and Tassos sent a technician within 30 minutes of seeing my message.
The bed was comfortable and I did not have any issues with noise at night. The kitchen has everything you need as well.
All in all I warmly recommend this apartment! Great value for the money.
