We interacted with Lisi during our stay (not Andrea and Daniel). The apartment was located in a neighborhood that seemed lively and popular with locals. It was within close walking distance to Madrid's tourist attractions, but it didn't feel too touristy.
The apartment was comfortable and had everything we needed for our last couple nights in Spain.
There was construction noise coming from the building next door and from a cocktail bar located downstairs that is open late into the night.
