We stayed in Chania for a week at Maria's place. The place itself is great with lots of space to relax and is completely independent with all its amenities. Despite being a flat it has great security and getting to the place was easy. We really liked the balcony which overlooked the city.
Maria was a very helpful host, she lives downstairs in the same building so is there in case we needed her. She showed us around the place and has a useful document outlining her own recommendations of things to do, transportation and places to eat. She even helped book a taxi for us when we were struggling with locations.
Accessibility is great, its located in a safe district and is about a 20 minute walk from the Chania old town, though the road is fairly steep (which wasn't a problem to us). Plenty of local supermarkets and small shops to go and buy food from.
Would highly recommend this place to anyone visiting the city, thanks Maria!
