We had a really great experience at Elizabeth's place, it's impossible to find a fault with this apartment. The location is about 10 min by taxi from the airport, 2 mins walk to the city centre and about 12 mins by bus to the beach.
She's a great host, and was waiting for us even though we arrived at almost midnight. The apartment is immaculately clean, and has far more amenities (including air conditioning for the heat) than we needed or expected. I will definitely be staying again when next I'm in Heraklion.
