The place i'd go to would be Zora's River from TP.
Imagine, 20 rupees for unlimited fishing with a canoe. Thats where i would spend many a days, its also within reach of Zora's Domain and Lake Hylia with canoe access from the boat house. And also Hyrule Castle as well. I'm sure i could purchase a canoe for permanent use for access to the rest of Hyrule.
I'm sure i could find accomadation in the boat house or build myself something in the fishing area.
