Rarely to Spain, but did not mind at all Spanish cabin crew onboard Finnair A321 to BCN and back last week. The service was efficient and friendly. The platinum perks behind the curtain were respected.
BCN has a very nice airport but the "VIP"-lounge is one of the worst, AY is using. Maņana-attitude at its best by the front desk. Offerings are very limited. Filthy bathrooms (or bathroom customers). The worst thing is the "free" wifi. Have to either pay or create a dubious account to a dubious source supplementing e-mail and personal details. Luckily I used one of my spare e-mails, which has been filling with personalised spam after that.
