Martin's Patershof Hotel
Mechelen is a Renaissance-era town in Belgium. It's in the Flemish part of the country, only a short drive outside of Brussels. Martin's Patershof is now one of Mechelen's most popular accommodation options, but it began its life centuries ago as a Franciscan church. When the building was converted from holy place to hotel, the stone pillars, vaulted ceilings and gothic accents were left intact. There is even a kind of "penthouse suite" in the top dome.
Patershof has earned high marks for its environmental friendliness. It has received both 14001 and EMAS (Eco-Management and Audit Scheme) certification. But Paterhof is most notable for its level of luxury. Some of the rooms even have private jacuzzis.
