One of the most interesting and vibrant places you must visit during your stay in Athens is the Flea Market in Monastiraki.
It expands from the Monastiraki square and reaches Thiseio and Psirri. The big fuss is mainly around Avissinias square where the heart of the flea market beats and the best day to visit is Sunday morning. The flea market consists mainly of small brocante shops but there are also street sellers mainly gathered in Andrianou street and around the metro station of Thisseio.
At the flea market, you can find literally anything. From trash objects to second-hand books and clothes, old magazines, newspapers, and photos to valuable antiques and vintage furniture. The flea market has it all! Prices are always negotiable and feel free to bargain without regret!
Apart from the shops, you can find cafes, small Greek and Asian restaurants. Be aware that some of those alleys and passages lead to beautiful secret gardens or terraces with fantastic views.
Last but not least, it is always a good and alternative idea to buy a souvenir from Greece that is beyond the ordinary and you will find plenty of them at the flea market!
