DO NOT STAY WITH JOANA! She will blame you (and try to charge you) for damage caused by prior guests!
We were visiting Lisbon from California and booked Joana's apartment for a four-night stay. On the first night, we noticed the bed wasn't very comfortable and was slightly slanted (lower on one side than the other), but we were jet lagged and exhausted so we didn't think too much about it and just went to sleep. In the morning, we both woke up with bad backaches, so we lifted up the mattress to see what was going on and found that the frame of the bed was damaged in multiple places and wasn't properly supporting the mattress. It also appeared that someone had tried to apply a 'quick fix' to the bed that had failed - replacing a damaged metal support beam with some plastic pieces - so it seemed clear to us that the owner or one of her staff must have known that the bed was broken.
We immediately reached out to Joana and let her know the bed was damaged, and asked if it was possible to replace it that day. She said she inquired with Ikea but they couldn't deliver a new bed until two days later. She offered for us to stay in another one of her apartments, but the most recent review on that listing said that apartment had a cockroach infestation so we obviously did not want to stay there. We informed Joana that given the circumstances, we would find another place to stay and requested a refund.
Joana only refunded us half of the cost of our stay, accusing us of having broken the bed despite the fact that we alerted her of the issue as soon as we found it and sent pictures showing that the extent of the damage was not something that would happen from simply laying down and sleeping on a bed for one night. Airbnb covered the rest through its Aircover program, thankfully.
Joana then sent us a reimbursement request for the full cost of a new bed, again accusing us of breaking the bed and saying that we owed her for the cost of a new one. To be clear: we absolutely did not break the bed, and the extent of the damage (metal support beam ripped in half, multiple support brackets warped and ripped out of the veener) was not something that could have happened from one night of normal use (and especially without the people sleeping in the bed noticing). Thankfully, again Airbnb support agreed there was no evidence we broke the bed and we did not have to pay for a new one.
The whole experience put a damper on our first couple of days of our vacation as we had to scramble to find another place to stay and deal with the back-and-forth with Joana and Airbnb support staff, but ultimately we ended up staying at a much nicer apartment, anyway. Minor in comparison to being wrongfully accused of breaking a bed, but you should also know that the hot water in the apartment ran out after a 3-minute shower. I would not recommend staying here, or at any of Joana's properties.
