my wife and I had a fantastic time at katerina and john's apartment.

we had good communication leading up to our arrival. we rented a car, and they directed us to an area that we could safely park for free that was a 5 minute walk away.

john met us at the apartment and was super friendly and helpful (tips on buses to samaria gorge and where to get out suitcase fixed).
the apartment itself is in an older building, but everything has been newly renovated. on the smaller side, but more than enough room for two people. and the balcony was great to relax in the evening.

you could not ask for a better location, located on a small road/alley (no cars), right in the middle of old town, a block away from the water/harbor.

the only downsides: the street that the apartment is located on is very lively, late into the evening, so it can get a bit noisy if you want to go to bed early. we ended up using ear plugs, so not a huge problem.

all in all, i would highly recommend this apartment.
