We came with two children ages 4 and 10 for a week-long stay and felt right at home. The location is great if you want to take advantage of the beach: literally a 3-minute easy walk through a nice little park (with good play options for the kids) and then straight to a wide public beach that is well-maintained. The Rambla, in the other direction, is perfect for quick food and shopping options. There's everything within 5 minutes from the house! Barcelona in general, and the Poblenou neighborhood in particular, is super veg and vegan friendly. We loved discovering the fresh produce in the area and using the well-equipped kitchen to cook at home. The metro line gets you to a lot of sights very quickly, just make sure that if you're with kids they know it's a bit of a walk. The bus lines in front of the house are very practical too, they head straight 'downtown'. It is a ground floor apartment so be prepared for some noise on the weekends, if you are a light sleeper some earplugs might be useful (mainly on Fri and Sat nights, the rest of the week is quite calm!). Local businesses are super friendly and the area has a nice, local feel, lots of elderly folks going out for strolls with their dogs. We were happy to have three separate rooms with doors, you could put the kids to bed and still enjoy some time in the living room. Highly recommended if you have kids and want to have a beach-focused holiday!
