I stayed at the Hotel Saint Jacques for one night whilst on a business trip.
The hotel is small, and room 7 where I stayed was on the first floor. As with many hotel rooms in Paris, the room was not the biggest but it was clean, well-appointed with free wifi, desk, two seater sofa and a flat screen TV. The room also had a small balcony overlooking the street below.
The bathroom was on the small side, with only a shower cubicle(no bath), in addition to the w/c and sink, but the décor was very good and it was nice to see good quality complimentary toiletries.
Breakfast was pricey at €14, and at 10:30am I was the only diner there. Breakfast is served until 11am. The staff were very polite and helpful.
There is a metro station less than 5 minutes’ walk from the hotel and the RER is few minutes’ walk from the metro station, and there are restaurants and grocery stores in direct vicinity of the hotel.
I would definitely recommend this hotel, and I would have no issues staying there again.
