PROS: Great view from the terrace. Lots of sun for people like to tan. Fun and eclectic decor. Close to some amazing restaurants and the Museo Reina Sofia. A 10-15 minute walk to Chueca and various parks and museums. Great for a couple or a family with one or two kids. Vin was a great communicator and greeted us upon arrival. A great value for the space overall. Would stay there again, but with a smaller group or with my partner. Everything we needed to make meals. A grocery store is nearby and a market which made things easy.
CONS: Just a few little things: a tight space for 5 adult friends alnd only one bathroom, but we made it work since we are like family. Lots of stairs for people that have mobility challenges. Clean, but not polished. Consider bringing your own pillows if you're picky. Needs new blinds on the skylights - very bright in the morning if you're a late sleeper and if you have someone in your group sleeping in the loft space. Perhaps an umbrella on the balcony or fix the awning for additional shade.
OVERALL: Would DEFINITELY recommend this place to young, unpicky people (e.g. the bomhemian backpacker or hipster couple who likes to have fun in a cool space.) We had a great time and would consider staying again if ever again in Madrid. Thanks Vin!
