What a lovely job you have done. We visit the Canaries quite often from the UK for a winter break, and I would definitely book with you.
Just a thought to add to all the great stuff already offered. Do bear in mind that you are starting pretty much in “off season” for the Canaries, with the rest of Southern Europe opening up for the summer season, i.e. greater competition.
I would change “yard” to garden as you have in one of your posts here. This is Europe!
