Alicia's apartment is very well placed to explore Madrid. It is very close to the Royal Palace and Opera and there are two metro stations within a couple of hundred metres. The central areas are really close so we walked much of the time, then used the metro when we were going further afield.
We chose the apartment for its location and also based on the photos which show a modern and quirky design within a period building. It certainly lived up to its images. It's a very comfortable space.
The area's a bit noisy at night (people returning to their apartments after a night out) but this is because it is in the midst of a vibrant city where the locals like to enjoy themselves.
We enjoyed our stay here enormously and would recommend it wholeheartedly.
