I stayed at this apartment for a month during a work trip with my work colleague, her husband, and my wife and baby. My mother-in-law also joined the mix for several weeks. The apartment was amazing, it's views, location and spaciousness were perfect for a full house of people looking to enjoy Madrid life. We never felt on top of each other and even used part of the living room as an office space occasionally. I would say the apartment felt a little tired and worn down so wouldn't go expecting 5-star quality. The bedrooms were a great size and being able to close off part of the living room for a 3rd bedroom was a handy option. The small additional bedroom, with sink, toilet and shower attached to the kitchen was very pokey and good for an easy going guest. The apartment management company were very helpful in sorting any issues that we did have. The apartment is in a great neighborhood with busy street life, however, being on the 8th floor meant for quiet sleeping, which was nice. The lift was also very appreciated with a baby and stroller.
Overall, we had a great stay and highly recommend the apartment.
