Pros:
- Nice flat, well located, AC, good sound-proofing.
Cons:
- Balcony has view on a... coach station though :)
- You'll only get half the flat if you book for a single guest for some reason, this was not clear from the description.
- Also, make sure you DO NOT send your passport scan, it's illegal for a host to ask for that and would infringe GDPR (I know Portugal has a requirement for hosts to verify and register their guests, but that's very different from storing and processing sensitive personal data -> be careful and say no).
