I cannot rate our stay with Silvia highly enough! This was hands down the best 'home away from home' experience I've had with Airbnb.
Silvia was so warm and welcoming and really provided all of the little touches that help to make your stay more comfortable. She provided us with information and maps and was available when/if we should need her.
As for the space, it is your own room with a bathroom in a separate part of the house. The views over Barcelona from your private terrace are amazing!
If (hopefully 'when') we come back to Barcelona we hope to stay again with Silvia.
