Bruno and his girlfriend Andrea were lovely and accommodating - they even gave up their personal bedroom for my use. The flat and everyone in it had a chill vibe, and I felt like my hosts trusted me to treat the place as if it were my own, so there was never any awkward moment discussing ground rules etc. It's a great place for people who want privacy/autonomy, and it's in the best neighborhood in Madrid - Malasaña. Would definitely stay again.
