Kat's place is perfect. The interior of the apartment is beautiful and very thoughtfully done -- the bed is in a loft but the real stairs (instead of a ladder) and the tall ceilings (so you can actually stand up) make it feel more like a second floor than a loft. The "downstairs" area is very spacious and great for relaxing after a long day of walking up lisbon's hills.
Kat was helpful and responsive throughout our trip.
