Filippos place is super! We really enjoyed the space and the mid century modern vibe. Great shaded terrace for morning coffee, and air conditioning in bedrooms for getting some restful sleep in the summer heat of Athens! Location was fairly close walking distance to historical sites, and downtown areas were reasonably accessible by foot too. There are some unsavory looking characters around the neighborhood (junkies) but they we're completely benign and paid no attention to us. If you prefer you can get an Uber pick up right out front and be in Plaka in a few minutes for about 3-4 euros...and avoid that scene completely.
All in all our stay was a great, communication with Filippos was a fast and easy, self check in was a breeze and he was always very accommodating and ready to help...Definitely would stay again!!
