Giorgios and Konstantina's apartment was great - the location was perfect, easily walking distance to all the main sights of Athens and had a great little square nearby that had some lovely cafes and restaurants and much more of a locals feel. The kitchen is well equipped and there's a lovely little balcony to sit out on. We were a little late showing up due to our train being delayed and hence had to make but Giorgios and Konstantina wait, but they were totally fine with that and were super friendly and helpful. If we're back in Athens we'll definitely stay again!
