I had a really good stay in the apartment. Marisol and Fran always responded extremely quickly to my messages and were very helpful.
The neighboorhood is well connected to the center with the metro just around the corner. My roommates were super nice and we got along well.
The only thing to note is that the room has its window facing the street. So if you're a light sleeper, you might be disturbed by the noise. It didn't bother me though.
Muchas gracias por todo!
