Absolutely remarkable experience. The location is among the best in Barcelona, right between Plaça Reial and Plaça George Orwell (30 seconds - 1 minute from both).
The apartment itself was very clean and super-well equipped. It is also very hard to find an apartment this large at an affordable rate in this part of the city. Despite the central location, the place is also absolutely calm as it is in a less frequented side-street and a bit towards the back of the building (here I would mention the only thing, which might be a downside for some people: The windows are towards a patio, which is very common in Barcelona and I know some people are sensitive to that, for me it was more than fine, as the patio is very clean and there is a lot of fresh air coming in)
Hame, at the same time, was the perfect host. He is very calm, friendly and competent. I had at one point an issue, with the tub of my shower leaking, towards the end of my stay. After I messaged him, he was in front of my door within an hour, with a new tube and a gripper and exchanged it within 5 minutes.
I can only give the highest recommendations, to try this place, as it wastely exceeded my expectations. I would be happy to come back, whenever the opportunity arises.
