How close are you to mass transit to the city center?
As for how to get into the city from the hotel, we are about 15km distance from the city centre and there is a variety of options to go there:
1- Bus #159 from a bus stop less than 5 minutes away, that takes you into Madrid (plaza Castilla) from where you can get any metro or other buses to move around.
2- Metro 'La Moraleja', which is an extension of the central metro lines of Madrid. It is about 15-20 minutes walking distance from the hotel.
3- RENFE CERCANIAS is the local trains that go straight into Madrid, this is the fastest option if you are going into the centre of Madrid such as SOL - Plaza Mayor (central plaza) as it takes 28 minutes from the town to the city centre. The inconvenience is that it is a bit further, approximately 25 minutes walking from the hotel (5mins by taxi)
4- If it is not Rush hour, taking a taxi into the centre shouldn't be much more than 25/35€.
There is a bus stop just down the road. (2 minutes walk). I don't remember a train station anywhere near.
