This apartment is very well situated, lively area, safe, close to supermarkets, bars, restaurants, very diverse and good for two persons, even though it has a sofa bed for a third person. It has the kitchen basics to prepare a quick meal.
The transportation from Barajas airport is easy, airport bus to Estacion Atocha for 5 euros and from there a 15 mins walk if you travel light or a taxi for 8 euros.
The Lavapies Metro stop is less than 5 minutes walk, one stop away from Puerta del Sol and 2 stops from Gran Via from where you can go anywhere you want such as Plaza Mayor, Royal Palace, Plaza Santa Ana and many other places of interest. The shareable 10 trips Metro card is a blessing for 14 euros.
The location makes it a great place to stay in Madrid.
