We had an amazing time at Spyros's place. It's location is perfect and we've spent the week visiting all of Athens's historic sites by foot.
There's a bus, tram and metro 3 minutes away which allow you to travel to the airport or the beach. There are also a small corner shop, pharmacy, bakery and a few local (less touristy) restaurants nearby.
Living so centrally in the heart of Athens, also means that it's not the quietest location.
The apartment itself is one of the best equipped places we've been since we started using Airbnb. It's also incredibly stylish.
