We had a good time in Daniel's appartment. As we have a one year old son, we can not really recommend it for families although they have a high chair for kids but it is ideal for couples.
Daniel and Ester were both very kind and helped us a lot when there was a problem or something needed. They were always reachable and answered very fast. Colonia is a nice place to spend some days. The city and the beaches are very easy to reach by foot. We especially liked the Indian restaurant which we can highly recommend!
