Barcelona is a very nice city and Montserrat's place is the perfect neighborhood! Literally minutes away from La Sagrada Familia, the place is actually very nice located to explore the city. We stayed for 4 nights.
Montserrat's daughter also welcomed us and speak very fluent English and help us to explain the house and the area. Their recommendations for restaurants are excellent (and Catalan's food is amazing as well) and the hosts are very warm and welcoming.
The space has a nice kitchen and coffee maker if you need- perfect to make breakfast.
Montserrat also give us a nice bottle of Cava (champagne's term in spanish) and a nice cup of chocolate.
We are very happy!
