This was a terrific base for our three-day stay in Barcelona. We are a family of three and this was plenty of space, well located with all amenities close by. You can walk to most things and are close to the tourist center without being in too touristy of a neighborhood.
The flat is well equipped if you want to cook (the kitchen is stocked with all the basics). If you want to eat out, close-by options abound. There are plenty of pillows, blankets, fans, heaters and everything else you might need to be comfortable.
The building itself is incredible, Google “House of Snails Barcelona” if you want to learn more. We would unreservedly recommend this flat to anyone looking for a place to stay in Barcelona.
