Alba was friendly and responsive right away. Unfortunately, we didn't get to meet Alba personally, but she arranged for us to get keys easily regardless.
Her flat is nice. Inside, she has a manual put together for her guests with tips, discount books, maps, etc - it's comprehensive. The area was convenient and not super-touristy. There were plenty of food options just a few blocks away, and there's a bus stop right in front!
Thanks Alba!
