Still undecided about what to do for Valentine's? I-escape.com, an online collection of small hotels, riads, farmhouses and retreats, has several last-minute escapes.
York House, a 17th-century convent in Lisbon, where labyrinthine corridors lead to uncluttered, beautifully designed rooms, has availability throughout February and costs from €150 per night.
Or how about the Hostal Abalu, just off the Gran Via in Madrid, which offers all-white designer rooms lit up in neon orange for €68 per night.
