Leaving our car in SdC

We are driving our own car into SdC and planning on catching a bus to Sarria - then walking back to SdC.

We have been advised that our best option may be to leave our car in 'secure' parking for the week at SdC airport. Just wondering what your thoughts are - has anyone done this? Would our car be safe there and would we get a bus easily from the airport?. Does anyone have any idea of the cost per day for this parking? (The only websites I can find are in Spanish ..)

I have read that there is a bus from SdC to Sarria around 6pm daily. We will be doing this on a Sunday - does the bus run on Sunday?

One last question . .. a recommendation for accommodation for our first night in Sarria prior to starting our camino. An albergue that's easy to find and has good reviews?

Thanks everyone ... Leanne

Thanks annie, david and falcon - there are some great links there. I look forward to having a closer look through them. Seems that the airport is a feasible (and affordable) option for storing our car - thanks for those links annie.

Cheers ... Leanne
