Right next to the Lavapies Metro station, and a bunch of great restaurants on Calle Argumosa which makes it really convenient if you're only traveling within the city. Trying to get out of the city to some of the outlying cities was difficult for me because I had golf clubs with me, and the neighborhood is not ideal for renting a car. So if you need a car, I would trust the cab drivers in the city to navigate the narrow streets. Pum Pum Cafe, practically next door, is a great coffee / breakfast place.
Inside the apartment is great, and the kitchen is incredibly useful especially considering you're a few steps away from a grocery store. If you're tall like me, the toilet facing the Washing machine in the bathroom is a little awkward :) but the Washing Machine was immensely helpful.
Overall highly recommend!
