Elena's place is great for staying in Barcelona. Conveniently located, at a couple of blocks from Sagrada Familia, and L3, L4, L5 metro stops.
The balcony room is awesome to have breakfast, or chill in the evenings if the weather allows.
Elena is chill and fun to talk. Also very open to share the other spaces of the apartment, which allowed for cooking and shared meals!
Quite recomended if heading to BCN
