The apartment was quite spacious and lovely, and a 2 minute walk from the water, restaurants, etc. Perfect location, and you can walk to everything. We were four people and it was more than enough space. Six people (assuming two of those are a couple) could sleep very comfortably (3 bedrooms, two with 2 single beds, one with a double bed).
The apartment was very clean and modern (lots of storage in the bedrooms) and the kitchen was unexpectedly well-stocked (even an automatic orange juicer!). There is a great little market directly across the street. Make sure to open up the windows at night and pull the blinds down in the day --the house does heat up during the day but it cooled off for sleeping, and there are many fans. Joaquin was very helpful and kind and communicated quickly. We would definitely stay there again (and wished that we could have stayed longer!).
