Free wifi also at McDonald's. Taxis outside start at 4€ usually enough to get you to the hotel…read moretourist zone. Don't be afraid, take a taxi instead of bus (cash 1.50€ plus troublesome). Metro not so close either and won't get you too close to the hotel zone.
The 4€ taxi is the starting rate, and when we took it to various places, it never went up unless you're going much further which I doubt since all of the places of interest are in the centre/downtown area.
For the City of Arts and Sciences, you can easily take the bus.
