My stay at Veronica’s was great- the place is very nice, comfortable, and very close to everything (the metro is a 5 minute walk, and Sagrada Familia is a 10 minute walk, for example). You can also take buses from the street the place is on to key sites (a bus took me straight to Poble Sec / Montjuic). Guests also have their own bathroom which is great when traveling.
Veronica was very friendly and allowed me to have breakfast and make coffee in the morning (she even offered some cheesecake she had made!). I would definitely recommend a stay here.
