Traveling to Barcelona for 4 days in early July.
Please recommend must see places to visit.
What places are better to avoid?
What are the best places to eat?
Any good day trips? How would we get there and back?
Should we stay in a hotel or look for an apartment to rent?
Is the hop-on hop-off bus tour worth it - or are trains and cabs better?
We do not speak Spanish, please take that into consideration.
Is it possible to drive in Spain, if we don't speak Spanish (understand road signs)?
