We stayed at Dimos' place at the beginning of our trip to Greece and then again at the end of it.
Dimos is an excellent host and very helpful. He made us feel very welcome and was able to provide assistance and advice about anything. The location of the flat is very handy and is the only one on the third floor, giving us a sense of privacy. There is a supermarket and bakery very close by. The flat itself is spacious and the balcony is enormous. We spent most of our time on the balcony enjoying Athens' sunny weather. The flat is well-equipped - even down to a range of toiletries you don't see in other places.
We were so comfortable here that when we returned to Athens after our trip around Greece, we felt we were returning home.
