I spent the month of October staying at Eleftheria's Suite in Marathi as a solo traveller, assessing Crete for a possible purchase of villa or apartment. I had not been to Greece off-season before.
Firstly, Marathi: Marathi is about 30 minutes drive from Chania, and maybe 15 minutes drive from Chania airport. Marathi itself, consists of beautiful beaches with rentable chairs and umbrellas if you choose (€8 for a pair of chairs) and several restaurants ranging in style from café to very good seafood. However, that's it. There is no shopping, not even for basic supplies. That means you need a taxi or your own rented car to leave Marathi and/or to get supplies. The nearest stores are in Aroni, approximately 8 km. away. I knew this beforehand, and had a rental car for the month, which was delivered and picked up to and from Marathi, which was painless. The road down to Marathi is hilly and curvy. Not a big deal to most people, but on the other hand, I planned to not do it in the dark.
Marathi beach is one of the loveliest beaches in Crete, and there are very few accommodations in the vicinity you can easily walk to the beach from. Eleftheria's Suite is one of them. As shown in her pictures, it is essentially a studio suite. The kitchen is fine. The little oven gets hot quickly and there are two hobs on top. The washing machine works great. The only thing I would change is getting a bigger refrigerator. Given that you can't shop easily, the freezer compartment is only good for making ice cubes, so not great for storing frozen food.
Bathroom is great. Shower has tons of water pressure and hot water.
The bed is awesome. I forgot to check the brand of mattress, but according to my fitbit, I don't think I've had as many 8+ hours nights of sleep since I was a child. The fresh air and exercise (and white wine with lunch) probably contributed, but still, I slept like a log (despite the number of dogs nearby and in Marathi who like to bark a lot).
The view from the room and balcony is as shown. Just beautiful. My jaw dropped the first time I saw a submarine sail by in the distance. Anyway, lovely view. Also, I didn't see a comfy chair inside when I booked. I asked Eleftheria, and she had a nice, comfy reading chair there when I arrived :)
These are regional issues, but there are occasional electrical brownouts and internet downages. If you can't have any wifi downtime, be backed up with your own mobile data (all the restaurants have wifi too). The one time Eleftheria's router really quit, her husband replaced it within an hour.
Eleftheria is a lovely, communicative host. I asked her if she was interested in selling her place, but I don't think she is and she is clearly very proud of owning her own rental place.
In summary, Eleftheria's Suite is a very nice place, and I would return there in a heartbeat. Thank you for your hospitality.
