If you are thinking of staying in Konstantinos don't doubt it and do it!
His place is perfect and has everything you need to cook in the kitchen, and even wash some clothes if you need.
If you are a walking explorer his place is very close to the acropolis city and museum, and you need to visit those two!
My favorite part was that once you are there the famous and cute area called Plaka was around the corner of Acropolis so it was really cool to walk the streets there.
Highly recommend it :)
