On a budget, weigh it — Mercer Hotel Barcelona isn't cheap for what it is.
€€€€ from ~€450/night
A hushed, history-soaked retreat where ancient stonework, a leafy courtyard and a small rooftop pool sit right in the medieval core. Idyllic for couples and culture-led travelers who want to be inside old Barcelona; tight on space and not for families wanting room to spread out.
