Julia was a very welcoming host and gave us great recommendations and advice on things like what to do around the city, a really good café for breakfast, and how to travel to and from the airport. The location was ~20 min from city centre but there were bus stops right outside the building, and a metro station within walking distance so transport was very convenient. The room was very clean and cozy with storage space, and the bathroom had all the essential toiletries prepared in case you forgot something. Saved us the hassle of bringing <100ml containers.
Overall, great stay and would definitely return if coming to Madrid in the future!
Note: there is also a lift we didn’t discover until the 3rd day, no need to climb all the flights of stairs to floor 5 every time.
