Mark and Marcela are very nice, helpful and friendly. The location is good, easily to get public transportation to old town(the famous attraction). It only take you about 5 min by foot. If you want to get there by foot, that is great, that is exactly what I do. I spent about 30mins walking along the streets which full of bars, clubs, restaurants and landmarks, if you are not in a hurry, I suggest you take your time and enjoy the city by foot.
