Best thing: Ideal location right on Las Ramblas, near Catalunya Square. Casual, funky place, with a little balcony with a lovely view overlooking the city. No separate key to the room, which might be a consideration for those super security conscious. I love pets, so delighted to have cat and dogs around, but not good for someone who doesn't like pets. Apartment on 6th floor; building had an elevator. Toilet and shower pretty cramped but good hot water. Host provided a bath towel and a key to the apartment to come and go at will. Again, the location was terrific.
