Emil was such a great host. When we first arrived in Barcelona, he gave us very clear instructions for how to get to his Airbnb from the airport at a late hour and waited outside for us to arrive. The first thing he does when you check-in is to give you an overview of the city, offer suggestions and tips, and answer whatever question you may have about Barcelona. Several times during our time in Barcelona, the advice he had given us came in handy or helped us save some money. Throughout our 6 night stay, he checked in regularly to make sure we were okay and had no problems - for example, when we told him we ran out of toilet paper he brought us some more immediately. For Emil, no question or need is too unreasonable and he will do his best to help make your stay the best it can be while always showing the friendliest demeanor.
As for the place itself, it was very clean and in a great location. There is a metro stop right outside, and a nice private little balcony outside your room you can eat on or just enjoy the view from. The room has a private bathroom inside it, and fully functioning air conditioning. The ONLY tiniest issue we had was that the shower is a little small (narrow, but tall). Maneuvering inside was a little difficult, and I can imagine that someone on the heavier side would find it manageable but unpleasant. It's otherwise very comfortable (temperature control and water pressure are both very responsive), like the rest of the unit.
Finally, Emil provides a small breakfast each morning in the form of a ticket for a croissant and delicious fresh squeezed orange juice (or a cappuccino, which we never tried) at a cafe downstairs called Can Rossell. This was a nice way to start each day because we didn't have to worry about finding food before beginning our activities.
Overall, I would recommend Emil's place to anyone visiting Barcelona. It is in a great spot, very comfortable, and comes with the added bonus of ultimate hospitality from a knowledgeable and friendly host.
