We were pretty dissapointed in our stay in this apartment. The only reasonable explanation we have is that we arrived when the host was out of town, and other people had to work instead. We never saw the host in person. For us this stay was more like a cheap hotel experience, than an airbnb experience.
The communications with the host in messages was shaky - we didn't feel like guests who were expected. We answered late or not at all, and not in a very hospitable manner. This created some problems for us - small ones, but problems nonetheless. And we had visited Athens before, it helped us. For somebody who doesn't know the city at all, problems could be bigger.
The conditions of the flat are not 100% as described. No tv, no washing mashine in the building, no shampoo (okay, a tiny tiny bit at the bottom of a bottle - not enough even for one use).
The wifi info in the flat was dated, which, together with the slow communication, created a case of stress for us. But when we got it working, it worked very very good.
The best thing in this flat is the rooftop, it's interestingly decorated, spacious and has some cosy furniture. The view is not magnificent, but it's a great place to rest and eat. The flat itself is okay. Very clean, nothing memorable. Kitchen has just the basics, you can't cook anything great here. Oh, the shower is very good - stable temperature, good water pressure.
Thit is not a bad place, we just can't understand how could it get the 5 star grades all around. As far as we know from staying in Athens before, you can find a lot better quality for the money than this place.
