The apartment looks exactly as advertised and is very close to the Retiro park. Even if the traffic on the road below is quite heavy, there is pratically no noise in the flat to hear.
There are many supermarkets nearby within a short walking distance. Also the "center" (where nightlife goes on) is to reach within 25 minutes if you are fast walking :) Otherwise, you might want to take the underground which is just next to the entry door of the apartment building.
If you arrive with car, you might shortly to park on the bus lane nearby. If you are looking for a safe and guarded parking place (if you want to avoid damages to your care), you might want to use the app parclick and book during your stay a parking house.
