Breakfast was poor in terms of choice of foods and the coffee was pretty disgusting (inexcusable in Italy). Hauling heavy suitcases up several flights of stairs since there is no elevator. This B&B plays on its location and charges accordingly but there is much better value to be had in more centrally located hotels which are not far away from all the attractions and transport hubs.
For us, the location of B&B4Rooms was excellent, being right beside two bus stops convenient for our arrival from Viareggio and our departure to Lucca, and, of course, its close proximity to the Piazza dei Miracoli. Air conditioning in the room was very efficient and quiet enough to leave on at night without disturbing our sleep. Although our room overlooked a busy road and the main access point to the Piazza dei Miracoli, there was very little disturbing outside noise (aside from a massive thunderstorm right overhead one morning!).
