I stayed at Romanos' place for two weeks, while working. It's a very cosy little independent spot by his parents' house, in their land.
Pros:
-Fantastic location if you want to get a local feel of Athens, about a 20 minute walk from Syntagma Square as well, so it's quite central.
-Comfortable bed.
-Clean apartment/bathroom.
-External area in the garden for enjoying the sunshine.
-Exceptionally hospitable hosts, Romanos' mother really felt like the kind mother who always makes sure you're well fed, very welcoming.
-Tons of nearby cafes, bars, restaurants, supermarkets, bakeries.
-Romanos was quick to answer any questions or concerns that I had, he was very knowledgeable about the local area, the city in general, and the ancient parts of the city.
Cons:
-Can be loud at night due to the bustling nature of the locale.
-The internet can be a bit spotty, but was still very usable for me - even when working full time from the studio.
-The kitchen is quite small, I found it rather difficult to cook there.
-Could be too small for two people, if you're planning on spending extended time in the studio.
I would always recommend this place for people looking for a comfortable, local Athenian experience.
