I recommend using your /home/Sites directory for editing the documents because it will be owned by the user automatically. Then add the user 'daemon' to the specific folder that needs to be writable by apache.
sudo chown -R daemon:daemon
or add the user to the group
sudo usermod -a -G groupname username
Or you can simply give yourself writable access or vice versa:
sudo usermod -a -G groupname username
