We had a wonderful stay in the Gracia district thanks in large part to Kilian. The train strike in France caused a delay in our arrival, but Kilian kindly waited for us, showed us around the apartment and gave us clear instructions how things worked. He then gave us insight on how to get around via the metro or hailing cabs. He shared places we might like to see, including restaurants within walking distance for tapas, etc.
The apartment was just what we needed. We were quite busy, so we didn't spend lots of time there, but it was quite comfortable and spacious. It was helpful to have laundry facilities, too.
Thank you, Kilian for being a wonderful host and being available for us as a resource. Loved our stay in Barcelona.
