The stay at Wilco's apartment was very nice. I booked one day in advance and he replied quickly and gave me directions. I arrived after midnight, because my flight was delayed, which was also no problem. My room was clean and the apartment is just 10 minutes away from the Sagrada Família. The small supermarket (long opening hours, open on Sundays) right across the street and some small cafés in the nearer region are also a big plus.
To be honest, I expected that his English is way better, but we came along ;)
