Ok, so what you need to understand is what to expect from this place. It is an RV, it has all the basic needs but it is not an apartment. That said, my girlfriend and I loved it. The RV is situated right next to the sea, the outside area offers a relaxing area and while Chania is a decent walk time away, it's still acceptable. The RV itself offers a decent sized bed, even for two, has a rudimentary kitchen and a basic bathroom. For those, who seek something different from a boring small apartment, this is perfect. We went there with the knowledge of spending most of our time exploring Crete, and for that it was beautiful. In our downtime it offered us everything we needed, as well as a beautiful view of the sea and a cozy living space. Yes, this is not for those who look for luxury, but man, I usually don't read and i could not help myself sit outside, listen to the waves, smell the ocean and just relax with a book and a coffee (or beer/wine). The surrounding area is very quiet, there is a small grocery shop around 15 minutes away by foot, or a Lidl a bit further.
Michalis as a host was very friendly and informative, anything you ask he could answer. You do need a car to get the most out of this place, but that applies for most of Crete. I've been to all-inclusive hotels before, I've been to standard Airbnbs that are just a boring room with furniture and not much more, but this place has character, and really stands out.
If you are looking for an experience, something more quiet and relaxing, I have to wholeheartedly recommend this place. We would have loved to stay longer.
