The Saint-Louis Marais is in a perfect location... there's both a cafe and a boulangerie/patisserie (bakery) a half block away and a Metro station (Sully Morland) about a block away.

Travelling solo and female, I wanted to be certain I was in a safe area. The Marais district is extremely clean, and the street that the hotel is on is residential and quiet, the hotel was a great choice.

As others have said, there's no elevator in the hotel, but after climbing the Eiffel Tower, Notre Dame, etc., what's a few more stairs?

There was someone at the desk at all times when I passed through, and they were always helpful and cordial when I had a question or needed assistance. A computer was available to be used by guests. I do wish I would've asked in advance whether the WiFi was free (it isn't).

I would definitely stay at the hotel again.

We spent our honeymoon at this hotel in Oct 2003. The room was small, but that's the standard for this price in Europe. The shower was tiny and the water pressure wasn't great, but I also found that to be common in European hotels for this price.
Yes, there are stairs and no elevator but that added to the charm for us. We are young and able bodied so this posed no problem. Our room faced a quiet Parisian street away from noise and traffic. We were very close walking distance to some great local restaurants, not frequented by tourists. We were also very close to a metro station, I believe it was Bastille. Another thing this hotel had which was very useful was internet access in the common area by the breakfast room in the basement.
Breakfast was delicious and carb-full, with fresh baked bread, croissant, and pain au chocolat. They must buy them from a local bakery. Orange juice, cheese, yogurt, and fresh coffee came with it, too. It was served to your table, not buffet style.
Before we checked out, there was a bit of a disappointment. We were on our honeymoon. The concierge who checked us out said "Oh, Friday (4 days prior) a woman from the States called to congratulate you and asked for champagne sent to your room. I wrote down the name and credit card on a piece of paper that I lost. I'm sorry. Be assured we did not charge the credit card."
Needless to say, when we returned home, we asked around and to this day do not know who the well-wisher was. The service and experience as a whole had been spot on until that moment, and it was an unfortunate way to end the honeymoon! Would we stay here again? Probably yes despite the forgetful concierge..

Although the Hotel Saint Loius Marais is rated two star (because it has no elevator and no air conditioning) the hotel deserves a three to four star rating in terms of comfort, service, charm and friendliness. We stayed in room 02 on the ground floor. Spacious and recently renovated, this room had enough space for our four (!) suitcases and their contents and both of us with room to spare! The bathroom is exquisite and with a full bath and shower. The staff are just delightful and went out of their way to help. Breakfast is served in the renovated "cave" and is copious - orange juice, pain au chocolat, croissants, baguettes, cheese and jams with excellent cafe au lait. The hotel has its own airport shuttle service and it has a computer terminal (for those who like to spend their time in Paris surfacing the net!). The location is excellent. A short walk from the Isle St Louis, the Bastille and the Place des Vosges. Our ground floor room was very quiet and we slept with both windows open (it was very hot in Paris during our stay). The neighborhood is quiet and residential and very safe. Jean-Michel and all of his staff are to be congratulated on providing for us a wonderful opportunity to stay in the heart of the Marais. We look forward to returning and hope everyone will enjoy their stay as much as we did. Bravo!

Having read the somewhat varied reviews of this hotel I didn't know what to expect. We had room 40, a walk up four flights of very interesting stairs. The room was great, with two levels (tiny steps to an attic room within the room). The bathroom was really nice - a great shower with good water pressure which isn't always a given in Paris, especially on the fourth floor. The hotel is in a quiet street, close to the river and the Marais, very close to the Bastille and also to the canal St Martin which runs between Bastille and the river. It is really a perfect spot - the metros St Paul and Sully Morland, which are really close, get you to where you want to be very easily - particularly the Opera, Champs Elysees, big stores like Galeries Lafayette etc. We didn't try the breakfast so cannot comment. The staff were also very friendly and kindly lugged our heavy bags upstairs for us - there is no lift. Having lived in Paris and visited many times, this was really the best room I've had there and for 125 Euros was not terribly expensive.
