We really enjoyed our stay in Barcelona and Fransesc&Laura's Appartement. Fransesc is really kind and help to feel well at arrival (kind attention : Orange juce in the fridge ;-)).
The appartment is very clean, plaisant et modern. It is well situated, near a station.
We've got 2 young children (5 and 7) and it was perfect. The beach is not far (10 minutes by feet) so we could manage between visits and farniente !
I recommend this destination and the appartment as well.
