Xenia & Valerian have an amazing, stylish and very practical flat in a great spot, right in the centre of Athens. We were greeted by Valerian who gave us a very warm welcome and made us feel at home. We stayed for 3 days and had a great time, as it is 2 blocks away from a central metro line and about 10 minutes walk away from Acropolis and other areas that are major sightseeing targets in Athens.
The flat has a very personal touch to its decoration, offers very interesting coffee-time reading materials (personal favourite: the bedroom poster on tree-grafting), while you rest from a morning's tour in the surrounding archaeological sites. Another personal plus was the well-defined separation for recycling and regular waste bins, which I haven't encountered before with other hosts.
I totally recommend the flat to anyone visiting Athens and looking for a 'steal' within walking distance from the city centre.
