The flat was very central, but the neighborhood was still quiet at night (there was a random dog barking somewhere from time to time, that was the loudest thing we heard).
The metro is just a few minutes away.
The flat was very clean and Pilar was very friendly.
The room has air conditioning.
The bed is a little small (I think that size is common in Spain), it was maybe 180cm or 190 long (so tall guys beware). Pilar had no problem with us cooking or using the fridge, we even could use the balcony and had a nice time eating there.
