We really enjoyed staying in Belen's apartment and it was super clean, well located and with plenty of extra touches (tooth brushes, dental floss, coffee).
The only issue was with the check-out. Previously we agreed that the check-out could be flexible and up until 2pm was fine to leave. However, I returned to the apartment at 1.30pm and there was some chaos with cleaning / preparing for next guest. The sense of being overwhelmed could have been prevented by writing in advance to let me know that the check-out time had changed and that the hosts were going to arrive for preparation before 2pm.
Apart from that, it was an excellent stay and I would recommend it to visitors.
