Katy and Luis were very welcoming and kind. They were very accommodating with the check-in time as well as check-out time; as out flight back home was quite late, the invited us to leave our luggage with them even after check-out so we could explore the city on our last day. Any questions were answered quickly and they gave us some tips to make our trip easier - from where the nearest copy shop is to how to best get to the airport.
The room itself is quite small, but they did their best to make it cosy and we were also welcome to use their beautiful terrace any time. Unfortunately, the window in the bedroom only opens into an roofed patio, so it was difficult to air the room, which did get quite hot. There was also the smell of food from other apartments coming through the window, so this is not ideal. However, Katy and Luis do provide a ventilator and there is always the terrace to get some fresh air.
All in all, they are wonderful hosts and we enjoyed our time in Barcelona very much.
