We can highly recommend Casa Altamira. The house is not large but the open concept makes the living area feel spacious and is comfortable for two couples, or one couple and kids. The living room has a working fireplace, the master suite is large and private, and the kitchen is small but well-designed and contains all the equipment necessary for serious cooking. The location is great. In particular, the plaza is 20 to 25 minutes and Fort Marcy Park is a mere five minutes away by foot. In addition, the surroundings are quiet. All in all, we were very comfortable, and so were our guests. Our only criticism is that the entertainment system was a challenge to operate given its numerous remote controls.
The house and its location are also great for dogs. There is a small fenced area next to the house where dogs can relieve themselves, and Fort Marcy Park is a good place to walk dogs and has a large grassy area where one can play ball (dogs are supposed to be leashed, albeit the rule seems to be flexible). There is also the Frank Ortiz Dog Park, a tract of a 100 acres or so where dogs can be off-leach and play with each other. The park is a 10 minute drive from Casa Altamira.
