It was very nice and just like described but unfortunately we had an unpleasant experience the first day when the previous guests had failed to check out in time and there was no time to get the apartment cleaned in time for our arrival. The host tried to solve it by offering an additional apartment for one night (which wasn't in good condition) in a different area and that brought down the experience. Other than that we loved the apartment in Veikou. The neighborhood was safe, well quipped, quiet at night and very central! Your basically a stroll from everything, like Monestiraki and the flea market. People were very kind when we asked for recommendations and other questions.
When I come back to Athens I would definitely consider staying in Veikou!
Best regards
