Not for children! This apartment should not be considered by people that have small kids. We received a complaint for noise every morning for 5 days. The host expects you to wear rubber shoes, provided by her, so that the people can’t hear you walking at night. If you want to talk after 23:00 or have kids that wake up before 7:00, this is not a place for you. These complaints spoiled our stay in Barcelona, unfortunately.
Apart from that, this is a very clean, very nice apartment with an ideal location. Everything you need is available in the apartment, and I hink it will be ideal for older people.
