Great choice! The flat is bright, spacious, clean and equipped with all the amenities required for a short or long stay (we stayed 2 months). In the neighbourhood, you will find bars, restaurants, bakeries and markets mainly frequented by locals. Plaza España is just a few steps from the house and so conveniently located to pick metro lines 1 (red) and 3 (green), which connect with all the places of interest in the city. Railway station (Sants) is also a few minutes walking and so perfect for daily trips.
Javi, the host, is a communicative and respectful person, readily available when you need. He even helped us to find a doctor when my parter was sick!
We are very pleased of our choice and, if possible, we absolutely repeat for our next time in Barcelona.
