Pros: Location was fantastic in terms of being close to all the fun and popular sites, very central, and everything within walking distance. Loved the gothic neighborhood, history, beautiful Roman structures, plenty of shops for supplies, cafes, and restaurants.
Check in location was very close and easy and it was very nice to be able to leave luggage. The space is perfectly fine for two people but might be cramped if more. Two full size beds were put next to each other to make one bed but could just separate if you wanted to. It was very nice to have a small elevator to the fourth floor after a long day of travel or walking. Neighborhood was picturesque. Internet speed was 80 MB/s which is pretty good.
Cons: The A/C was not working our first night but they sent someone the next day. The neighbors upstairs were really loud. They kept moving furniture around that would scrap the floors and make very loud noises which would wake me up. Also, people would party until 3 AM or later and it would get really loud outside. Partying into the early morning hours is typical in Barcelona as we learned. We could hear all the noise even with the window closed. Luckily we were so tired that we were able to go right back to sleep.
