Comfortable, traditional house in a great location, ideal for a car-free holiday. We stayed with 4 children, including teenagers. We loved walking in the nearby Collserola hills and then getting a quick train into the centre of Barcelona for sightseeing or an evening meal. The trains are really frequent and very clean, and very cheap. The house was very clean and is furnished with everything you need, and is lived-in enough to be comfortable for a family; it feels like a real home, not a show home. Nice views over wooded hillsides out the front and a large informal garden for kids to play in round the back, going up several terraces. There is a ping-pong table and equipment supplied.
You can find good recommended walking routes on the Wikiloc website, and some maps at the Collserola Park Information Centre, which is just down by Baixador de Vallividrera train station. This is only a 20 minute walk from the house via a safe walking/cycle path separated from the road - or just one train stop, though the walk is nice. Our favourite walk was to Baixador then up through the woods to Tibidabo, where we had lunch with fantastic views and looked round the church and amusement park and enjoyed spectacular views. Wikiloc is especially helpful for walks as it has photos of the track, so you can see which trails are rural footpaths and which are minor access roads. The regular maps are a bit sketchy on this and seem to omit some nice paths.
Font des Planes is a local Catalan restaurant which was good value and friendly - nobody spoke English so we improvised!
No shops in the village, but a 10-minute train hop to Sant Cugat and you can get the Mercadona Supermarcat, which is large and has a great range of foods. Sant Cugat is a nice small town to visit, with some excellent artisan bakeries and delis, and some nice cafes.
In summary - a great option for those who want a car-free holiday with both countryside and city culture. Best of both worlds.
