Overall we had a brilliant time at this apartment with our two young children (2 and 5). The apartment is right in the centre of Kissamos, round the corner from the Archaeological Museum, so really handy for the morning bakery run and nice to be in the buzzing heart of the town (although sufficiently quiet at night). Location wise it's also very well placed for exploring most of Western Crete.
The apartment is spacious, with two twin rooms and a double, so plenty of room to spread out - although the bathroom is on the small side. The beds were well made up with immaculately clean linen, with plenty of extra blankets provided, but the double bed in particular is very hard so some might find it uncomfortable (we did). The kitchen is sufficient but when we visited there was only one pan that wasn't huge, so cooking was a bit challenging - although we mainly ate salad so it wasn't really a problem. There are two balconies which between them see the sun pretty much all day. The one at the front has a low wall/railings so young children need to be closely supervised. Anna and her partner live downstairs some of the time so are on hand to help with anything and are very friendly and hospitable.
Despite the few drawbacks mentioned above I would definitely visit again and do highly recommend this apartment to other visitors.
