One of those rare occasions where pictures don't fully show how gorgeous these views are. Anna's place is quiet, private and beautiful. No loud parties, no safety concerns.
Yes you can walk to Park Guell from there, it'll take you around 15 minutes. Guess what? If you're in a walking mood, you can easily hit Sagrada as well. Don't forget an amazing science museum within 20m walking distance as well. For 6 euro entrance this is just unbeatable. Down to watch a Barcelona game? Say no more, metro will take you to Camp Nou faster than you would've waited for taxi or Uber.
Now little disclaimers:
- privacy comes at the price of walking up the stairs. While walk in itself is short, it may be not an easy one if you're having any health issues or disabilities
- there's no large supermarkets within walking distance. I doubt you need them, since a couple of smaller stores will stock you up for breakfast, but still, keep this in mind
