The apartment is definitely great!
Me, my wife and our little 1 year old daughter stayed there for ten days and I say this is definitely a perfect place for both families, couples or any other type of travellers.
Thalis, the host, met us at the supermarket SYNKA which is located at Platanias square (type in Google maps "Cafe Diogenis" or simply "Platanias" and you see it there, won't miss it). From this supermarket it is 5 minutes walk and there you are at apartment.
For us the apartment was great since the kid had lots of space to run around. Thalis has cot bed, baby chair and this made our stay even more convenient !
The beach is 5 minutes down the street but this is not the best as we see it! We had a car for rent (which we definitely recommend when you are at Crete since you could go to any beach) and the car park is right here in front of the apartment door.
We personally found Kalatha, Beach Canteen Iguana and Falassarna beaches as the best for us, but we were choosing only from sandy beaches appropriate for babies. At Kalatha you can find a renting point for sups, kayaks and the guy there is polite and the price is appropriate, the equipment is good.
In general, Thalis and his family are very welcoming and friendly to guests since Thalis mother always gave fresh vegetables (tomatoes peppers) and figs from her garden as welcoming treat and Thalis is ready to help any time!
So you feel yourself as at home ))
