We've had a nice stay, but the place is a bit slapdash. The apartment is really spacious, clean but rather old and unmaintained - you'll see a lot of cables here and there, some broken amenities (corkscrew, shower curtain, kettle, etc). WiFi was sometimes worse than mobile. The garden is nice, with fine view except the junk yard around the place. The pool is clean but with some strangely designed fall behind, which is rather dangerous for children fooling around. There's nicely arranged space around grill oven which made one of our best dinners there. Note, in order to get to the apartment you need to cross the other apartment's yard and our neighbors didn't seem to be delighted about it. The owner was nice and welcoming, very communicative.
All in all - not bad, but for the price we've seen better. If not the Matala it could be easily forgotten. Not the best place for children I'd say as you need to be alert at all times (cables, pool). Also some little investments could make it really cozy. Though if you don't plan to stay in the house a lot, like to have a grill at the pool and Matala is your must visit destination - it'll be fully satisfactory.
