With a group of nine people (all aged 55+) we stayed at this place for 5 nights. We had a great time. The apartment is huge, with big bedrooms, and several clean and modernized bathrooms. The kitchen is very well equipped. In the apartment building there is always someone around to help. Grand Vía is the border between the big shopping streets and the smaller, and, to us, more interesting restaurants and shops. We visited the big museums on foot. The only downside was the weather, which prevented us from spending long hours on the two terraces overlooking the city. Fantastic place!
