I only saw Lú briefly when I checked in, but it was a nice room in a good location, especially for the price. You could hear through the walls pretty easily but it wasn't a problem at night because everyone was in bed at a decent time and the neigbourhood got quiet after that. The mini fridge is next to the bed like a nightstand and you could hear it humming, but it was nothing earplugs couldn't fix, and the convenience of having it and a tea station was very useful. I would stay at Lú's again, but just make sure I contacted her about check-in a day or two beforehand because it took a bit to hear back from her on the day of.
