Was very inexpensive (1/3rd the price of other hotels we stayed in in Spain) and located with a beautiful view of the monastery in El Escorial. However, on day 1 our bedroom had no tables! The TV was on the floor, and no side tables. We thought it was kind of funny and maybe fitting in terms of proximity to the monastery. We were told at the front desk that there was no wifi that would reach our room. We were mostly thrilled to have a room with air conditioning after 90 degree July day. However, the bed had an extremely thin mattress and no mattress pad, so the comfort level was akin to sleeping on the floor.
Things improved in day 2 - we got the wifi password from a more helpful staff member at the front desk as I tried to work downstairs and found that the wifi range did extend to our 2nd floor room, though it was somewhat spotty. And when we returned to our room for the second evening, we were pleasantly surprised to find tables.
So, we probably would have had a better experience had we demanded it, but no overcoming the thin mattresses.
