We really enjoyed our stay at the apartment of Ana & Oscar. Mostly because of its good location we were able to walk almost everything we visited in the city. The public transport is as well really well organized which helped us visit some places outside the city. There are some good places to eat nearby. Be prepared for noise from people going out and walking home late at night (but we expected this somewhat because of the good location).
The communication was good and we enjoyed the ability to make our own meals at the apartment. Thanks again!
