The flat is spacious (but a bit dark). It's very well located (near Llacuna metro station, close to the beach, plenty of cafes, restaurants and shops around, and within easy reach to other areas of Barcelona) - so it's a good enough place for a few days of sightseeing. There are refurbishing works happening from 9am in the morning in the next door building during the week. If you are a morning person, the noise shouldn't be much of a problem. If you are intending to stay for more than a few days (for example, a week), have a lay in in the morning and if you can't function without a decent morning coffee, I'd suggest you find a better place.
