Our stay at Nektapia's house was great. The house easily accomodated our party of seven. There's a lovely expansive view of the mountains of Crete and a side view of Chania's Old Town on the south facing balconies on the main floor and second floor.
My wife did yoga every morning there outside. No flies or mosquitoes disturbed her during her practice. The north facing balcony on the second floor offers a view of the sea. The bedrooms have air conditioning, a welcome feature because temperatures hovered around the 90s during our stay in Halepa. It's a 45 minute walk to the city center. A cab ride to Old Town for one person ranges from 5 to 7 euros, but for 3 or 4 people, about 10 euros.
We did walk over on our first day and it was pleasant. About 15 minutes into our walk, we actually came across a path to the water near a restaurant where we found locals swimming. That's one big highlight about the house's location, you get to mingle with the locals. We discovered a charming bakery called COUCOU close to the house that offered excellent breads and pastries made fresh every morning - simply a must to visit.
If you are into American cuisine, there is a very nice burger restaurant called Legends within 3-4 minutes walking distance. Hamburgers are huge and reasonably priced. I recommend eating there at sunset, the views from outside seating are amazing.
