If this is available, you should book it now! The location is great. Right next to one of the best walking streets in Barcelona, with plenty of shops and booths, performers, squares, food, and an amazing farmers market just a short walk away. It's a quiet location, but not far from great nightlife if you are interested. There's a beautiful rooftop for hanging out, and the apartment has everything you need for a night in.
The host Lili is super helpful and kind, she's knowledgeable and has plenty of suggestions for things to do nearby or around the city. She is wonderful to talk to, and I enjoyed our conversations just as much as I enjoyed Barcelona! I promise, you will not find a better stay in Barcelona. Highly recommended!!
