I had never stayed in Lavapie but I was familiar with calle Atocha and surrounding area. The apt was a small studio perfect for a weekend getaway. Very clean, wifi worked perfectly, so did the a/c.
You can walk to Puerta del Sol, Plaza Mayor, Atocha train station etc.
Train station Anton Martin is the nearest metro stop.
To get to the apt you have to go down a street that is a steep hill and going up the hill can be a challenge with luggage, you also walk a flight of stairs to get to the apt. If this isn’t an issue then it’s the perfect little spot.
