Argyo and Theo were both lovely. Super fast and friendly communication. Theo waited for us even though we were late for check in and was really relaxed and easy going when we got there. They were very Greek in their hospitality - they had a freshly made cake for us and Theo even dropped off a lovely gift for our baby!
The apartment is really styley. It's in the 'Shoreditch' (London) of Athens. There are lots of great bars nearby and some excellent restaurants. One of Theo's recommendations was a taverna with the loveliest people and fantastic food. The other had a really nice rooftop garden with a view through the gasworks to the Acropolos. It felt very Athens 2015. Also Monastiraki is only one tube stop away - we had some great food and shopping.
Theo's apartment has great traditional Greek stuff (warm hospitality) plus great modern Greek stuff (style/edge).
Highly recommended!
