Our experience was excellent. Sergio was proactive and did the arrangements in advance to welcome us late at night. It was a very warm weather and it was very nice of him to have something cool to drink at our arrival :) Small details do the difference: he made sure we had everything we need to keep the place clean and nice with no additional cost.
About the place itself: it has great daylight! Also, basic essential amenities (microwave, washer machine, iron, hairdryer) that make life easier. It is conveniently located, just one block away from subway and several bus lines, and near to downtown ("microcentro"). Groceries stores, cafés, and wonderful restaurants are all over the area.
I would love to stay there again!
