This was a great apartment to explore Athens from! It was clean and spacious, and nicely decorated.
The check-in instructions were fantastic and we had no issues there whatsoever. We did find to key to be a bit sticky in the lock though, just as an fyi for others.
Somehow we managed to walk everywhere without using the metro, but most of the touristy stuff seemed to be about 25 minutes away or so - I'd recommend using the metro to travel around unless you enjoy walking.
There are plenty of places nearby to grab a bite to eat or to have coffee, which was handy, and there was also a nearby ATM. Also - on Fridays, there's a local market just steps away, so that was really great!
We loved our stay at Eric - Helen's place!
