Wanda was a wonderful host and tried her best to make us feel welcome! While the apartment is small, it is definitely suitable for three/four people. Some things were missing in the apartment (enough towels, etc) and it can be a bit cold at night. The neighborhood is very eclectic and not touristy at all. There are a ton of small good restaraunts a couple minutes walk. It's a local feel so if you care to be in the very center of Madrid i wouldn't recommend it.
