What to do in Madrid? Well that's a big question and one which requires an even bigger answer. Perhaps since I've lived here for so long and know the city so well, it's harder for me to answer. If you have a good guidebook, have a look and decide what most fits in with your interests. Then look through all the posts on this great site for tips an extra information. If you're only going to be in madrid for a few days, you won't have time to get too far off the beaten track. Remember, the big attractions alone would take more than a few days to get through. But feel free to get in touch with any spacific queries or for any specific bits of advice. See you soon.
