The house is pretty, very spacious and functional, equipped with everything you might need!
I worked from home for three weeks and A/C and high speed internet were a blessing, the flat can be a little noisy, but it's a small price to pay if you consider you are pretty much in the centre, without the hassle of being in the middle of the touristy area!
The are is super nice and friendly, lots of good restaurants and bars in Exarcheia and a 20 minutes walk from Syntagma square and Kolonaki.
For me the best feature was the proximity with Lykavittus hill, which I went to every day for breath taking views of the city. Overall an amazing place for a very reasonable price and an outstanding host, super reliable and a great communicator.
