We would highly recommend Picasso Suites 5.3. Check in/check out was flawless and the most organized and professional experience we have had on Air Bnb. The apartment is clean and modern and as pictured. Breakfast was included at a nearby cafe which was a nice feature. The location is great if you are looking to stay in a quieter part of the city but still close to all the main attractions (about a 10 minute walk to Sagrada Familia and 30 minutes to Gothic Quarter). We were able to walk to most sites and the metro is also very close. The initial connection to wifi was a bit slow and kept dropping but once it connected it was fine. We would stay here again if we are ever in Barcelona.
