Great host and location for stays in Barcelona, and is reasonable in cost compared to what else is around - not too far away from the city centre by bus/metro, so is convenient & quiet in that respect. The area is well facilitated if you did want to stay nearer the property. It is still a busy street but once inside the property, there's no noise at all from outside to disturb you if you like the quiet.
Emilija was very accommodating and as an introvert, I felt more than comfortable asking for anything I needed during my stay. Her English is great which helps if your Spanish is lacking, like mine!
Overall, it's still someone's home so things will look used, because they're meant to be! It's no 5 star hotel but match your expectations to what I've just said and you'll love it. Personally, expectations were exceeded and I would recommend it to any solo/couple travellers in Barcelona.
