The host was very helpful, our plane was delayed and he had to wait an hour longer for us and he did not complain, he even met us at the bus stop! He had lots of tips and told us the best places to go. The city felt safe overall as long as you are aware of your surroundings. The apartment has a perfect place to sit on the balcony and drink tea in the morning. The building is older but everything works great! My only complaint is the bed was very firm but it was the same mattress we found in Santorini so that might be what people sleep on here which is fine. I will be staying here again hopefully when I return to Athens!
