I spent a weekend here. Luz is a very kind and welcoming host, and this compact suite is a work of art itself -- there's a good chance you've never been anywhere quite like it.
The bed's comfortable, the shower's good, the kitchen's functional, and the communal garden is charming (and peaceful when the neighborhood's quiet).
Sound from other suites carries easily within the guesthouse, so if others aren't so good about keeping their voices down, you'll have difficulty ignoring them.
The suite is windowless and offers little sense of the outside world other than street noise, so depending on your preference, this could be good or bad.
