We stayed at Sven's apartment last week in February.
Some reflections:
1) Communication - very smooth. Sven gave us all information (about apartment, places to eat, etc.) we need before arrival
2) Location. Usually we stay in hotels or b&b during travels, but when you are in Barcelona for the n-time - it is definitely a reason to "act as a local" and to rent an apartment. Besides, Gracia always draw our attention as a place to live due to its charm.
So, it was a "win-win" choice.
3) Apartment. Very beautiful, cozy and charming. So many interesting details as floor tiles, old door, marble sink in the bathroom, rainshower, cloakroom. Not to forget about gorgeous view from the kitchen - to the left: orange tree; to the right - mandarin tree; just amazing!
What could be better than sitting at the balcony, drinking wine and listening to the music on the square?
But be careful with "staircase of sobriety":)
The only issue we can mention - as a tea lovers, we were unable to find a kettle to heat water:)
Overall, this experience was very pleasant and we can (and will) absolutely recommend this apartment for living in Barcelona.
