Fantastic location for walking/exploring the neighborhood. Lots to eat/drink/see in 30 min (walking) radius. Very comfortable place (bed/kitchen stuff) with a distinctive character.
Even though it's slightly below the ground there's still plenty of light and sun during the day! The walls are somewhat thin, so you can hear the owners upstairs if you're sensitive to the noise (wasn't a problem for us as Clementine and her family were out during most of our stay). Fast communication and very accommodating hosts.
