I really enjoyed Felix’s flat. It is in a very safe location in Madrid between to prominent metro stops. I’ve traveled to Madrid many times and this location was ideal for me. I stayed in the piso for one month. It does have a vibrant night life surrounding it but it is only loud on Friday and Saturday nights. The rest of the week it is very quiet during the night hours. It’s comfortable and Felix is very kind and quick to respond. If you’re looking for a safe and practical stay this one is for you.
