An excellent choice for your stay in Athens! The apartment was exceptionally clean, the bedding was nice (and the mattress is great btw) etc.
And it has a nice patio!
The one minor point is every 15-20 minutes the tram loudly passes in front of your window but this is fine if you use a pair of earplugs. But if you are sensitive to loud noises just be aware. :-)
Besides it was a perfect stay and I had everything I needed even the little things.
The host is amazing too, he is always in touch and responds super fast in case you need to contact.
Hope to stay there again!
