Edu's apartment is in a great central location, if you're looking for something right in downtown Barcelona. He was very friendly and responsive. We were able to let ourselves into the building and apartment. The building has a small elevator (big enough for two people or one person and a suitcase), which was a nice luxury after lugging our bags up stairs all through other places in Spain. The apartment is big and modern and nice looking at first glance. Our major complaint was the cleanliness. The walls were scuffed and smudged all around, and there was a big red wine stain on the kitchen ceiling. The bathroom and kitchen both looked like they needed to be better cleaned. The shower and faucets were grimy and in need of a good scrub, perhaps regrouting in the shower. There was a big patch of mildew or soap scum on the shower floor. There isn't much storage in the bedroom for clothes and the like. There is a flimsy shelving unit; the shelves are essentially on a fulcrum and wobble when you put anything on them (stuff could easily fall off). Edu did email me regularly to check in and ask if we needed anything. I didn't mention the issues because it didn't seem like there was much he could do by the time we were in, but I have mentioned the issues in my notes to him. Finally, he offered a lift to the airport for 50 euros, a "door-to-door service" that he insisted most people take him up on because it's so convenient. But 50 euros seemed especially steep. We opted instead to use Mytaxi (an app similar to Uber or Lyft but that works with city taxis), and it cost us less than 30 for the same service.
In short, the apartment was a good value for the location and was perfectly comfortable for our needs since we only spent mornings and nights there. Edu was super nice. If I go back to Barcelona, I wouldn't totally rule out staying there again, but I would be more likely to try a different place.
