Konstantinos is one of the friendliest and most helpful hosts I've ever encountered through Airbnb.
His apartment is in the most perfect location, right in the heart of the city with easy walking access to most sites.
Konstantinos is more than happy to recommend great bars, restaurants and museums which made my trip a great deal more enjoyable.
The apartment itself is very clean and comfortable, and also very quiet despite its central location.
I'll definitely stay again when I'm back in town.
