What an amazing apartment! Javi is the best host I have ever had; he is what one could consider a legend. The flat is super clean and tidy, the room is ample in size, the bathroom is super rad, and the terrace is ideal for breakfast and late night beers.
The position of the flat is ideal; you are within easy walking distance of two metro lines and countless bus routes (buy a multi-day ticket or a multi-trip ticket; you can easily catch the metro into town from the airport if you don't have a lot of luggage). Add to that, you are so close to all the hotspots that you can easily grab a cheap can (download Taxify app for convenient cab hailing -
you can pay cash or card for those unfamiliar). Everything you need is 15-20 minutes away by public transport. There are great restaurants close by, the Sant Antoni market, and two High Streets within walking distance (Parallell and well kitted out one).
Again, Javi is such a rad dude. He made my wife and I feel at home instantly, and all of this through the use of Google Translate (download the app) as Javi knows a tiny bit of English (and my Spanish is shockingly bad).
Barcelona is an amazing city, with incredible food and the most hospitable people. Staying with Javi just elevated it to a whole new level.
