Konstantina was a great host - quickly responded to any questions and shared many local recommendations. The flat was clean and looked like in the pictures.
The only issue was the location - there's quite a lot of drug users on the streets, they didn't approach us at all and I felt fine when I was with my friends, however, I'd rather avoid this area if I was by myself.
The flat is very close to the centre though- we barely used public transport as you could walk everywhere.
