Basti was friendly and accommodating for my late arrival (train canceled so I got in around 11pm). He charged me 20€ for my late arrival, to pay the flat mate for letting me in, but I understood as it was last minute.
He communicates via whatapp, which at first made me nervous, but he was nothing but helpful, kind, and quick to respond.
The room is a great size and fully furnished for everything one would need. The bed was really comfortable and a descent size. Towels were nice, and there were beach towels available as well. A downside was how hot the room was (no ac) but the fan made all the difference, especially for sleeping at night.
The room is in a flat shared with other people so the bathroom, kitchen and common areas were not private. Everyone I encountered was friendly and respectful. The kitchen has a shared brita (water is not drinkable in Barcelona) so this was convenient to have, and everyone was respectful in keeping it full after use.
Unfortunately the room smelled of cigarette because it shares a wall with the patio; but after traveling through euro and staying in hostels, everything tends to smell of cigarette.
Location was phenomenal, right by the metro and bus!
