A great place, located in a highly convenient place in the middle of Athens - nearby market offers many options, inc a 24*7 and multiple restaurants/coffee shops.
Stevie is very prompt in his replies, and helps a lot with questions related to local travel/random touristy stuff. Also, he appears to have put in a lot of effort in decorating his place - which might be little small, but has been stocked nicely with all the stuff you might need during your stay. Definitely, a great value for money!
Would love to recommend this place to others; and even stay there again myself should I come to Athens again.
