Miguel's apartment was more than we could asked for. It is beautifully decorated and very clean. It is conveniently located near a Metro station, so getting around town is a breez. There are a lot of very good restaurants and shops nearby. For us one of the main reasons for choosing Miguel's place was the location: away from the crowds, but so easy to get around.
The only things about the apartment that could bother some are the noise from the neighbor above (sounds like someone is using a walker) and the firmness of the mattresses. For the american people that are used to sleeping on a pillow top mattress, the beds are on the firmer side. But that is normal for Europe. So, you just have to get use to it.
We would definitely come back.
