In short: immaculate, very well equipped for our stay, superb location, excellent communication.
The long version: looks like new. It is the best prepared place we have stayed in, which tells me that the host is very thoughtful in that she anticipates very well what's needed in the apartment to make you feel at home. Nicely close to all the tourist spots of Athens, and to public transport. Many taxis pass right in front or you can call e-hailing service. The walks to Acrópolis and surrounding areas are a joy. You will find so many good food outlets, coffee shops, bars, taverna, grocery and mini marts, shopping, beauty salons, etc. Don't miss out on the Friday morning farmers market at your doorstep, or the bakery which is 50 steps from the apartment! Would definitely stay there when I go back to Athens.
