Our family had a wonderful 5 night stay in Aglaia's lovely house in August. We have two teenage children (boy 14, girl 12) and the house worked perfectly for us.
The location could not be better, in the old town, a 1 minute walk to the bustling waterfront with the choice of all the restaurants.
We were met on check in by Aglaia's mother, who explained everything to us, answered any questions we had. She had even left some supplies for us (bread, eggs, milk, juice, fruit) which was a nice touch.
We were there during a hot August (up to 35C), but the air conditioning made it a real haven to come back to and cool down. And the wifi was adequate for two teenage kids!
The beach is less than 10 minutes walk away. And there is free car parking nearby if you are driving. It gets busy at weekends, but I never had more than a 5 minute walk back.
There is a rooftop balcony to sit out on in the evenings, though we preferred to sit outside the front door in the shaded alley with all of the other locals.
I'm sure there are more positive things I could write, but you get the point. We highly recommend this location if you are visiting Chania.
One very minor point. When our taxi driver put the address into Google Maps at the airport, she was directly to an incorrect location downtown. It's best to mention that Ritzou Andrea is off "Theotokopoulou", the main pedestrian street through the old town. And note, this is a pedestrian street, though the taxi can get you to within about 50 metres of your destination.
