It looks like visitors to Madrid will now be able to get tourist information from a new Tourism Office. Situated in the famous Casa de la Panadería, in the Plaza Mayor, the office will be open from 9.30 a.m. to 8.30 p.m. According to the Esmadrid website:

"The centre has arranged six internet access points allowing visitants to look up – through the esmadrid.com website – the new Tourism Board database,
developed by the city council-owned company Promoción Madrid. This new
venue provides as well the visitants with WI-FI (wireless) access
making available Internet access through portable computers."
