Federico's place was fantastic overall, but with a couple of notable disadvantages. I love the Gràcia neighbourhood where it's located. Central but away from the crowds of tourists, with plenty of fantastic local cafes and restaurants. The neighbourhood used to a be a separate town outside of Barcelona inhabited by artists and other bohemian types. It still has that character and is just beautiful. It's a short walk to the metro which gets you into the centre very quickly. The flat is much more attractive than many flats I've decided in, with bright decor and even including nice artwork. I was afraid it'd be freezing - I was there in winter - but not at all; it's well heated. The bed is comfortable, which is a must for me. Federico was very responsive and very kind. The main disadvantage was that the wifi often didn't work at all. When it did work, the signal was very faint and could only be accessed from the back of the flat. As I was in the flat for three weeks and needed to join calls for work, this was a real problem. I was refunded 100 euros by the host, which was much appreciated. He says he plans to switch to a new wifi provider, so this may get fixed soon. If having good wifi is important for you, I would check this first. The other disadvantage is that there's a notice in the bathroom saying the hot water lasts for 10 minutes. In fact, as long as you avoid putting the water onto full power it lasts 7 or 8 minutes. Great for the environment I know, but I have long hair and it was winter. That said, this is a cosy, attractive, well equipped flat in a fantastic location with a great host. I would certainly come back on the condition that the wifi had been fixed.
