I stayed at Fiona and Phil's apartment with my family for four nights.
I have no complaints whatsoever! The place is perfectly located in the heart of Barcelona; it's big, cozy and clean.
Phil and Fiona stayed in touch with us for the duration of our holiday and they were always available in case we needed something (which we didn't: the place is furnished with everything you could possibly need).
Truly amazing hosts. Helpful, professional and nice. Highly, highly recommended :)
