¿Are you looking for a nice room in a quiete flat close to the center?
Then let me know. I am renting out a double bedroom. It has a very good infrastructure. Buses and metro to the center (Retiro, Alcala, Goya, Atocha, Sainz de Baranda, Ave. de America, etc. …) are close by.
If you are interested, then let me know. Write me a mail with your number and I will get in contact with you.
