finding room in Madrid asap

I need to find a room with a double bed from February to May in one of these areas: Legazpi, Palos de la Frontera, Sol, Plaza de Castilla, Lavapies, Nuevos Ministerios, Cuatro Caminos, Castellana.

My budget is 650 maximum including everything (utilities fee and management/contract fee). Feel free to text me via WhatsApp. I would love to have a look at the room before signing the contract.
