Got some late cheap flights from Bristol to Bergamo for a surprise trip for my Wife and I (£60 for 2x return flights with Ryan Air) and then set about finding a hotel for the long weekend on tripadvisor. At the time, the Mercure showed up as number 1 hotel and the Best Western as number 2... due to their being only particial availability for both hotels for the three nights required, i was able to test both (2 nights Mecure and one night Best Western).
the Mecure was a good quality hotel, as i have found with the brand in the past. staff were very friendly and the location is ideal- close to station, buses and funicular). bedroom was comfortable and spacious, although a slightly strange shape (with low ceilings in places- top floor roof beams) and a very odd colour (very strange blue). only average value at around £100 a night and it could of done tea/coffee making facilities. you won't go wrong with this good hotel, although i prefered the Best Western, were i got a better deal and an upgrade (although staff wern't as nice).
