Theo's place is superb and I will stay again there if I come back to Athens. The apartment is in Monastiraki, which is not as developed as Placa or Syntagma and can be a bit of a shock for some people, but it is a lot more unique and lively, and there you can really get a taste of the real Athens. The apartment itself is super cool, decorated with a lot of taste and the facilities (beds, showers, kitchen appliances etc) are all of high quality. I also loved the leaflets, cards and lists of recommendations provided by the hosts to make sure you know where to go and what to do. Very easy checking and fast communication whenever I needed them.
