Apartment was an excellent location, directly in front of the Monumental metro stop. It was also very close to Sagrada Familia, and the restaurants on Avenue Gaudi. The host uses an app on your phone for your keys that works great, but getting it set-up takes some effort.
The apartment handled our family of five perfectly, with enough beds and we were able to catch up some laundry with the washing machine. The kitchen is equipped with the basics. While the apartment size was great, we would just describe it as basic. The entire place was kitted out from Ikea, nothing was special about it. We would not stay here again based on the beds being so uncomfortable... they were the stiffest foam I've ever encountered. Thank you for the ceiling fans they were a must, as the place was quite warm, we used them all night and often slept with the windows open to the traffic.
Bottom line, while the location was excellent, we would have spent more money and looked for a place with better comfort. We spent most of our time out of the apartment exploring the city, but would have appreciated coming home to sleep better.
