Welcome Tobbria,

In respect to accommodations, it may be well worth your while to look into the Bancotel system which allows you to purchase coupons that cost 50 euros per night for a double room in 3,4, and at times 5 star hotels over all of Spain.

As Puna mentioned, if you do a search of BANCOTEL you will find many threads explaining this fine system.

I stayed at the Suecia in Madrid a 4 star hotel for less than 50 per night.

saludos,
Carmen
