There seems to be some confusion here. Yes, the building is open to the public, since it is a branch of the Banamex bank: hardly worth checking out the interior therefore! Best walk round the side into Canal for a glance at the original portal and the exquisitely carved doors. Howevere, I cannot see how this gets listed as one of San Miguel's top attractions.The other review (in Spanish) is under the impression it's a hotel. It's not.
