It gets cold and dark in Spain in the winter too!
If you buy somewhere in a complex with a swimming pool, it will be empty and soulless in the winter. You will also need to check out what facilities are still open. If the complex has a supermarket, it's likely that place will be closed too in the winter, so how far will you need to travel to get groceries? If you live in a town, where there is some life in the winter, you will probably forgo a swimming pool, which will be nice to have when the weather improves.
As for price, if you bought somewhere for €35k in Ireland, it is probably in the middle of nowhere or in a crime ridden area. The same applies to Spain. You will really need to do your homework on the area that you are buying in. No point in living in an area with a drug problem or an isolated place where you don't meet anyone.
I would keep the capital and spend it on being able to move around the place. If you get it wrong one year, you just don't go back. If you love it there, the landlord will be perfectly happy to book you in for the following year if you are block booking for months.
