Stayed at the Sonoma Hotel for three nights and found it comfortable, pleasant and welcoming. The staff were helpful in a friendly yet unintrusive manner, the room was charming and the location was fantastic - right on the main square and next door to the excellent Girl and the Fig restaurant. Highly recommended.

The Sonoma Hotel's greatest attribute is it's location - right on the square. The rooms are small, and others walking around on the floor above us was quite obtrusive. Coffee and pastries in the morning were very good, but there were only 2 small tables for everyone to share/sit at. It's clean and safe, and that's about all I can say.

Right on the square in Sonoma so ideal and good price (from $175 depending on room), although remember that it is a good price for Sonoma where everything is overpriced and don't expect the room you'd get elsewhere for that price!
My room was in the cheapest band and tiny (just about room open open the case on the floor), other rooms looked far nicer so worth paying the extra for a better room.
Separate wash basin in the room (with dripping tap) and shower and toilet in a tiny bathroom.
No wi-fi but rooms on the front could get wi-fi from places across the street.
Just pastries for breakfast, good but no choice or fruit available - good breakfast at El Dorado Cafe across the road.
Biggest issues was the heating in my room, it was freezing when I checked in and no way to fix the temperate. Tried several times, asked various staff (morning staff very helpful and evening girl could not have cared less!) but had to sleep in sweater, facing away from air vent and with ear plugs in to avoid noisy from air vent and dripping tap!
Great meal at Cafe le haye - reserve far in advance.

I stayed, note not slept, at the Sonoma Hotel on 10/4 & 10/5 and while the hotel was nice, the service was nonexistent. After a rain storm passed at 3am on 10/4 all that could be heard was the sink dripping like Chinese water torture. They gave us another room the next day, but they should have fixed the sink before giving us the room. At 3am on 10/5 we were awoken by the loudest tv you've heard. Called the front desk at 3:30am to no answer. At 4am I had to walk around a find the room with the TV. Thankfully the drunk had left his room open, so I went in and turned the tv off and went back to my own bed. The next day, all the staff could say was, "I hope you sleep well tonight." I thought to myself, of course I will, because I won't be at your hotel!
