Paolas Studio is located in the center of madrid (close to puerta del sol) which is nice because all of the major sightseeing spots of the city can be reached by foot, which means there is no need to spend money on public transport. The Studio is clean, well equipped and has everything you need. Should you still need anything else Paola will try to provide it, she Even booked us a taxi to the airport.
If you are planning to explore Madrid i can highly recommend this place.
The only thing that could be problematic is the fact that the walls are quite thin which means that you can get quite an insight into the lifes of the neighbours.. it might happen, that you hear kids crying at 4 oclock in the morning. But over all this place is really recomendable.
