This is a Airbnb you must stay at.
Location: The location is perfect. It is 2 min from the metro stop and surrounded by great restaurants, bars, little super markets, and etc. there are such great places to eat right around it- Qimet & Qimet, Bar Celna, Asian Way, and on and on. We were amazed at how great the location was. It was a 10 min train ride to La Rambla and the metro stop for the Funicular de Montjuïc up the mountain.
Airbnb: Very secure as you have two front doors with keys to get through. The flat is tastefully decorated with Japanese culture. They put time and energy into the decorations and it shows. We loved it. It had all the things we needed and more. The bed was comfy, the two rain shower heads were wonderful, consistent hot water, cold a/c and a washing machine. It was one of the best we have stayed at.
This is a great place to stay. Book it!
