This is one of the better Airbnb's I've stayed at! It was very clean, functional, and tastefully furnished. George is a great host too.
One personal touch I loved was being able to connect my phone to the vintage sound system through my phone, the sound reminded me of an old stereo I used to have as a teenager and being able to listen to my music made me feel more at home somehow.
The location is a bit further away from the "action", which can be a bit annoying if you're doing a short trip and want to be spending lots of time in the city centre. It's a 30-45 minutes walk there (not recommended in the summer), a 20-30 minute bus or metro ride or a 10-15 minute taxi ride. Honestly it didn't bother me much and I appreciated the opportunity to see an Athenian neighborhood where only locals live and see a different side to the city. It was also a nice change of pace from the hustle and bustle. So like I said, while it's not really a negative in my book, I think it's important to be aware of this before booking.
