Jon,
Thanks for the clarification. Some additional information.....
At the station in Monterosso, you'll have to navigate stairs to get from the train platform down to street level. I've never counted them, but perhaps 20 stairs? Once you're at street level, go left and walk along to the tunnel and Hotel Pasquale will be on your left when you exit. You can get some idea on the layout by having a look at THESE photos. This is the view from near the tunnel looking back towards the station. It's not a difficult walk as it's mostly level. Many of the larger hotels there (such as Pasquale and Villa Adriana) have elevators, so keep that in mind when you book.
At the station in Riomaggiore, you may have stairs depending on which track you arrive on. You may have to go down into the underground passage to get from the platform to the station plaza. Again, maybe 20 stairs down and then up? From the station plaza, you'll walk through a tunnel that parallels the tracks to get to the main street. There are no stairs there (unless you're going down to the harbour), but there's quite an incline on the main street. As many of the buildings there are fairly old, it's likely that many of the B&B's there will also have stairs (the one I stayed at several years ago certainly did).
Regarding the prices at Hotel Pasquale, THEIR WEBSITE shows these prices. It's a very comfortable hotel and AFAIK all the rooms have ensuite. If you'd like to have a look at some of the other places in Monterosso, have a look at THIS LIST (it should be reasonably current). THIS B&B seems to be very popular, but I don't have much information on it. They don't show prices so you'd have to contact them for a quote.
Happy travels!
