I had a great 3 night stay at Stella and Nico's apartment. The place is located in my favourite area in Athens, you can literally walk in all the sites and also is very well connected by public transport .
The apartment itself is very nice, well equipped and super clean.
The terrace with the tub was the best spot.
The communication with the hosts was excellent, they responded in every question and also sent messages to check if everything was fine and needed something.
A real gem in the centre of Athens, I would definitely recommend and come back.
