Javier is a very warm welcoming host. The apartment has all the basics one needs in a quiet spot of Marathi which is nice location facing south and protected from the winds which often blow west or north in Crete. The place is literally 5min from the closest sandy beach which is nice for a swim. He had some nice suggestions. My favourite was Seitan beach (but take some comfortable shoes as you will need to descend a steep rocky path, not too hard, and go from the right side of the beach behind the little shrine. Everybody seems to go from the more obvious left side but I thought it's much more difficult path for me after the first 50m)
We were lucky to have the whole place for ourselves. We had the appartment with a leaving room including a nicely equipped kitchen corner, a separate bedroom and a small shower room/toilet comfortable enough. There is also an outside common eating table next to the swimming pool with a big barbecue, a big sink, a fridge and all kinf of pots and cutlery as well as oil, salt and spices
Javier also generously left us a jar of sweet lemon confit which is a local specialty
The place is basic, simple and not sure about the farm stay description but if you want a nice base not far from Chania and other sites, then Javier's will be a great spot and he's a very nice man too.
