Anita24, can you find a map of the city of Granada there in Westland? That might help. I've never been to Granada but I've seen photos and it's DEFINITELY a city. It's no little walking-village, that's for sure. And they don't have a metro so the only way around is by bus or taxi. I'd have to GUESS, maybe GranadaGirl (or others) can help you here more than me, that the bus system they have there is efficient and frequent.
And what/where is "the Carmen"? Do you have an address or website for this place?
AND HEY! Just for kicks, I GUESSED and found
http://www.GranadaMap.com . The main, overall map is pretty crude but it's clickable and this allows you to ZOOM in to the different sections, see street names and iconic graphics of important structures/monuments. (although most of them are not named)
Anyone else? Good luck, Anita24! Saludos, MadridMan
