I stayed at Joan's place over the course of fall. I had an excellent stay here as everything was just perfect.
All the basic essentials are covered - I had my own private room, private toilet and had access to strong wifi and a shared kitchen that is spacious and well equipped.
The balcony was definitely a huge plus, where I spend my morning and evenings doing basic exercises, read and have my meals. What's more, one can even do their laundry and dry them in the house!
The location is also very strategic. It's near to the supermarket, pharmacy, mini markets, bakeries etc. More importantly, it is very well connected to nearby transport connections:) (Metro and Bus)
The host, Joan is also super helpful and kind. Although English is not his first language, he always tries his best to help me when I face a problem. He's amazing!
All in all, I had a great stay here and would 150% recommend it to everyone looking for a long stay in the lovely city of Barcelona :)
