My wife and I stayed in Isabella’s place for one day only and it was great.
Isabella was very polite, puntual for check-in, and always accomodating with our needs. She was quick to respond any question we had from the beginning, including before booking and throughout our stay.
The flat is in a really nice neighborhood: it’s safe, it has lots of nice shops nearby, restaurants, transportation options, supermarkets, all within walking distance.
The place itself, in our opinion, was better in person than how it appears in the photos. It was clean, elegant, cozy, modern and all around very comfortable to be in. The Wi-Fi was good and reliable; the bed was firm but comfortable (we would have liked it to be a bit wider, but not much of a problem), the Shower alone should get a 5-star review. it was great.
The Air conditioning was solid good. We went in August —hot weather— so it was perfect; it cooled the place very quickly. The kitchen had the necessary utensils, including a stovetop italian espresso coffee maker. There were small details that were nice like, when you open the small door under the kitchen sink where the trash bin is: that little compartment was scented, which was surprisingly nice.
Objectively, the only negative thing we noticed was outside of the scope of the flat itself. Because it’s a big building we heard occasional loud neighbors arguing. There’s no way for us to know if that’s common or not, but that was our experience.
In any case, we had an excellent stay, and we will definitely keep Isabella’s place in #1 spot when we consider visiting Madrid again.
