Love that it allows for in-depth learning on the go. A great replacement to the traditional structured (and a little stifling) tour group. Meli's a fun way to explore and learn on work trips, when backpacking or travelling leisurely without a guide.
It worked perfectly for my little hometown as well as Paris and Amsterdam. It's the perfect app to discover little details around us or have a personal audio tour for famous places and monuments. Big plus : I ordered my skip-the-line tickets directly in the app and it was cheaper.
