We raelly enjoyed a two nights stay at the tiny rooftop flat. the rooftop is amazing and you have a great view over Athens! Everything you nee for daily life is in walking distance. The metrostation is in walking distance as well and its located in the lively neighbourhood Gazi.
if you are not used to citylife and noises you'd better bring some earplugs.
we will defenetly recommend to stay there because its a really good Place to start your adventure through the beautiful City of Athens.
