Buenísimo!! Frederic is such a wonderful host - he certainly went above and beyond to provide us with the utmost hospitality. When we had issues with the Internet, he was out of town and came all the way back to Barcelona just to let the technic in, and it was resolved immediately! Any request we had, he was at our door in literally minutes.
The flat itself is very comfortable, the beds are great and the AC is strong, though it gets pretty cool at night so it is comfortable. The only thing that gave me a bit of a fright was that the windows do not have screens on them and the flat is very high up so if you have children, be very careful when the windows are open and watch them carefully.
The location is super! 15 minutes walk from La Sagrada Familia and great restaurants and supermarkets all around. We would most certainly stay in this spacious flat again, and highly recommend it to other travelers!!
For anybody working remotely like us, the internet was excellent - at a minimum it was 130MBPS upload and sometimes higher! Outstanding! Thank you Frederic!
