The flat is very spacious, centrally located and is just as described on the website.
Although the flat is on the ground floor of the building, the street is a residential one and on the quiet side. Shops, supermarkets, restaurants and bars are all nearby and within walking distance to many other attractions. The great thing about Madrid is that one doesn't really require public transportation within the centre and everythig can easily be reached on foot from the flat.
We unfortunately weren't able to meet Eliana in person, communication with her was always very pleasant, quick and she was easy to reach at all times. The check-in and check-out procedure is really easy and hassle-free and doesn't require her physcial presence.
Most definitely a flat worth staying in in Madrid, especially with more people, as there is plenty of space for all.
