The apartment itself is nice. It is one of a block of four in a very small village about half an hour away from chania.
Our experience here differs from most I think as we came in March, and this apartment is not really suited for the off season in my opinion.
The main reason is heating and water. We stayed for a month, and in March the weather is not that great, and can be quite cold at times.
The apartment does have radiators, but you are not allowed to use them as they are expensive to run, so you have to rely entirely on a single air conditioning unit in the main living space, which isn't big enough to heat the whole flat, so the bedrooms, bathroom and most of the living space remain cold. Also this unit regularly blew a fuse and stopped working when it actually started to hear up.
The water is supposed to be heated by sunlight, so we were without water for several days until we eventually contacted the property manager who told us we could take turn the electric water heater on but only for half an hour a day before we shower, leaving us with cold water most of the rest of the time.
The location is also not great. Again I think this was made worse by the fact that it was the off season, but the surrounding village is extremely with only one real shop that has limited options. The apartment is a 5 minute walk from a very stoney beach so not idea for sunbathing. You can walk 15 minutes to the next town over, or get a bus half an hour to chania. Otherwise, it is a necessity to have a car here or else you will feel very isolated.
Another thing to note is obviously although the apartment was advertised with a pool, it wasn't fill for most of our stay due to the weather, so bear that in mind.
We also had a few power cuts during the stay and sometimes the WiFi was a little unreliable.
On a positive side, the owners were very welcoming. They did not speak any English at all which made communicating issues difficult, but they were very friendly and provided a good selection of supplies when we arrived.
I would say this apartment is fine for a family or a group of friends in the Peak of summer who have a car, but if you come in the shoulder season or lack transport, you would be better off in chania or close by and make sure the utilities are working properly.
