I spent 5 nights at Hotel Mario's in July 2017. I selected the hotel based on Tripadvisor reviews and the location. My room was a single with private bathroom. The room was not large, but comfortable with AC. Breakfast includes cereal, yogurt, pastries, fruit, cold meats, cheese, juice, coffee, and tea. They will also make a plain or bacon omelette on request. Hotel Mario's is upstairs and there is no elevator, so this may be a consideration if you have a large amount of luggage or difficulty going up/down stairs.
Just a couple of blocks away from the train station, the hotel is easy walking distance with luggage. The front desk staff are friendly and helpful, providing recommendations of local restaurants and sights.
I enjoyed my stay and would stay here again.
