I was at a party in Barcelona. What surprised me a lot is how their public transportation system evolved. I can see way more places showing the timetables and when will be the next bus. Metro seems to be developing too.
A lot more people are using bikes and in general this city is friendlier than ever towards tourists and visitors.
Barcelona is a thriving city, unlike some that languish. If you want to have a great product, make it easier for your customer to feel right and feel safe and feel that with their abilities, they can navigate.
If you do that, the product will be easier to advertise and reach a wider audience, because your current visitors will be your fans and will write good words for your products. This is what I am doing now about Barcelona.
