The stay at Carlos' flat was overall enjoyable and as advertised.
If you have access to data, the check-in and access to the building and flat through a link is super practical! Eliminates the need to get the keys from someone etc. However, if you are coming from overseas, you may not have a local sim card / access to data , so plan accordingly.
The instructions for this "self-check-in" were very clear.
In addition, I noticed a bit at last minute that check-in was at 15h00, and we arrived sooner, Carlos very helpfully allowed us to arrive within the following half hour without any issues. Thanks for the flexibility and responsiveness!
The flat is very well kept for the most part, with some minor fixes which could be done in the bathroom but nothing major.
Flat recommended!
