Lyonel was responsive and helpful all throughout. He was not in town but arranged for us to be welcomed by his friend who was nice and showed us around.
Flat is located in a quiet and local street which is super nice; a perpendicular street (carrer de Blai) is 1 block away and full of restaurants attracting many tourists but also locals.
Metro (subway) is nearby and Montjuïc teliferic is very close.
We walked to many places from and to the flat. It felt nice to be close to the city's attractions but staying in a quieter/more local area.
Flat is perfect for a single traveller or couple.
