Helder was very understanding when asked about flexable check-in/out times, and made our visit to Lisbon a lot easier. Allowed an early check-in due to early flight arriving in Lisbon, and allowed us to store out luggage in the accomodation after check-out before a late night flight - Allowing us to fully enjoy our last day!
Accomodation was everything we needed. Nothing too extravigant, but perfectly fit our needs and budget.
One issue was that the power often went out in the apartment, likely due to a faulty appliance tripping the electric. But after notifying the host, it was a simple reset of the fuse box - as instructed from the host.
