Montserrat is an amazing place, magical and wonderful. Hotel Abat Cisneros is located in a historic building next to the Monastery, with a sublime view. The rooms are very clean, comfortable, beds and pillows equally comfortable and clean.
The internet works well and besides the splendid location (next to the Monastery) the hotel has a 5 star restaurant, with extremely refined food, well done and very well served, as well as tasty. In my opinion, even in Barcelona is hard to find a restaurant like this, with a great wine list and impeccable service. It is practically on top of the Montserrat Museum, a beautiful place to visit, which has a collection of religious and archeological articles and articles as well as Catalan painting, in particular a beautiful collection and paintings by RAMON CASAS.
It is also very close to the funicular Santa Cova and Sant Joan, possessing one of the most beautiful views of Montserrat and Monistrol, just below. With good weather conditions you can see the Mediterranean sea and Barcelona by day, like Barcelona lights and sky stars at night.
Do not die without visiting Monserrat and staying and dinner/lunch at Abat Cisneros !!!
