I stayed at the Helvecia apart hotel for 6 nights while at a conference in Santiago. The hotel is located in a very nice area, only a couple blocks from two other major hotels (intercontinental and double tree) and is very close to a major shopping centre (constanera centre), which has pretty much everything you could possibly imagine. From the hotel, it is very easy to travel around using the metro Line 1, which is located within a 5 minute walk. Many restaurant options in the area, well within walking distance. The staff were friendly and security was present 24 hours per day. The room itself was huge, much bigger than I needed and included a living room, dining room, and kitchen, just as advertised online. I would recommend this hotel to anyone looking for a discount option when staying in Santiago, as the major hotels can be quite pricey.
