I stayed one month in Kikis place and it couldn't have been better. The apartment is super nice and in a quiet area of Athens.
The roof terrace is sooo nice! You have a great view and it's a perfect spot to hangout or do some sports.
If you want to work there, keep in mind Internet is not suuuper fast, but I helped myself with mobile connection,what was really good.
The communication with Kiki was soo nice! She always replied so fast and was the perfect host.
Highly recommended this flat!
