First and most important - hosts have to answer the phone when guests are checking in.
This should be a front page rule of the entire airBNB - when guests arrive, hosts must have someone human available to answer the phone.
The apartment is well intended, but a bit awkward - it feels institutional, these are converted medical offices, or something like that.
The entry locks and lockboxes are complicated to navigate - and if you don't understand some Spanish to read the instructions, forget it.
in addition, the lock upstairs on the floor to the apartments is old and failing, so it took many tries, to finally make it work - not what you need after a stressful day of travel.
The apartment is clean and well equipped - but some tea and coffee packets in the kitchen would be nice, a bottle of water, some thoughtful basics.
The location is very good.
This stay is not a failure - but it's an awkward experience, and the host's indifference is a drawback.
