Rowena and Thanasi have created a lovely place to stay in central Athens. The apartment is spacious, clean, and furnished to a very high standard in a minimalist style.
The apartment is situated in a quiet building with a balcony onto a secluded courtyard. There is a supermarket and an excellent coffee shop right outside, and it's only a 5 minute walk to the Syntagma square metro.
Rowena and Thanasi have written a really useful pdf guide which they sent us in advance, and included recommendations for restaurants and bars. We visited two of their recommendations, and both were excellent. In particular, we'd suggest Te Kaffeneo for an authentic meal. The cheese pies were brilliant!
Thanasi met us at the apartment for check-in, and very kindly brought some home-made pastries as well.
Over all, we couldn't fault our experience staying at Rowena and Thanasi's, and we'll be recommending their apartment to friends and family for future trips.
