We stayed at Andrea's appartment for 5 nights and it was a great base to explore athens from. The location means its easy to get to by public transport from anywhere including the airport and is close enough to walk to most of Athens tourist site's in under 30 minutes and also a great selection of restaurants right on the door step. The flat is nice and comfortable space with all the amenities you need for your stay and Andreas is a very helpful and responsive host. Check on and out was simple. Obviously the location means that there can be more noise at night from the busy street below if you're someone who likes an early night but it's certainly not unbearable.
