I payed somewhere around 4,500 pesos per month in Plaza Florida Apart Hotel back in 1997 or 1998. Last time I checked (one year ago) for people my company brings monthly, they were charging around 20,000 to 25,000.
They have a lil kitchen with a big refrigerator, dining set, living set, queen/king sized bed, some of them balcony, cable tv, A/C, hot water/electricity 24/7, daily maid, linens included. Bathrooms have been remodeled 1 or 2 years ago. They have opened a lil restaurant if memory serves. Anyway, they had Boga Boga Restaurant downstairs. It is always neat clean. I think it is the most decent apart hotel in Santo Domingo.
Other apart hotels in Santo Domingo I have stayed during trips before moving here are Drake and Turey. Cheaper but decent enough apart hotels. Drake is in Piantini close to Plaza Andalucia. Turey is in Naco near Amigo super market.
Plaza Florida beats them big time though. It is located close to Universidad Catolica de Santo Domingo, a couple of blocks far from Lincoln Ave. I dont know the neighborhood's name, it could be Serralles or La Julia.
