We really enjoyed our stay at Alex's appartment. It's not very modern or luxurious but if that's not what you need, this apartment is perfect for you!
It has everything you need (and more) a fully equipped kitchen, bathroom with shampoos..
There's a big supermarket only a few minutes walk away, you can also walk to the main atractions wich are about 30-40min walk (on your way you also go through the national garden of Athens) If you don't like to walk too much, there's a metrostation 13 minutes away.
Alex is very helpfull, he picked us up from the metrostation, gave a lot of usefull information and recommandatons.. the perfect host. :)
