This flat was perfect for my family's stay during my wedding week. It was huge enough for our group of 15 adults. It was close to the Urquinaona metro and walking distance to Plaça Catalunya. There was no air conditioning in 3 of the small rooms but we kept the doors open and the AC from the common area, dining room and the other 3 bedrooms helped cool it. We had tons of help when we needed it, communication was superb. We were also able to leave our bags after checkout because our flights were late in the evening. Overall, great place to stay for a large group, don't expect luxury but it's definitely a clean and comfortable space to be in during your stay in BCN.
