Stayed at Vassos apartment in Athens and I was pleasantly surprised! The location is ideal for walking around and seeing all the sites and there are some great restaurants right at your doorstep! The only thing I would have to say to be aware of is the size of the bathroom as the shower/toilet are pretty much on top of each other. It wasn’t an issue for me as I was solo travelling, but for reference it was a tight squeeze. Would definitely recommend for someone travelling alone or a couple!
