Finally, after months of searching the internet, discussing with my sister and mother (the first is coming with me, the latter will babysit my two daughters while I'm away), I have booked the flights! We will be flying with Ryanair from Dusseldorf to Sevilla on February 7th, and coming back on February 14th.
I have bought my Spanish phrasebook and am trying to arrange some Spanish lessons for my sister and myself. We don't have much time I know, but some Spanish is better than no Spanish so we will try to get the basics down at least!
At the moment I am looking into hostel accommodation. I will be booking this over the next few days. Unfortunately there are no reviews on hostels in Seville yet so I will have to take my chances. I will write about whichever one I end up staying at so at least there will be one review on TB!
