We stayed at the apartment for one night on our way to Barcelona. The check in was quite easy, although it requires having an app to unlock it, or you have to meet your host.
The location is close to the train station and about 10-15 euro Bolt ride to downtown/fun area.
We were quite disappointed to find that the apartment wasn’t really cleaned for us - dirty towels in bathrooms, showers were dirty and one didn’t have hot water at all and had a blocked sink on top of that. Hairs everywhere and ants in the kitchen.. so, I’m not sure if it was a one off or a trend, but we didn’t find the cleanliness to be there at all.
The bedrooms were quite spacious and mattresses/pillows were great, so we had a restful sleep. AC was only in one bedroom, and fan in the other, so keep that in mind.
