Made the mistake of booking this tiny studio apartment for two of us who work from home.
Check-in is at 4pm (not 3pm) but the apartment wasn't ready until 6pm.
When we arrived, we immediately told the host that the place would not work for us because there is no bedroom door, so working from home and both of us being on conference calls would not work.
Host did not offer any concessions, nor offer our money back even though we told him within the first two hours that the place wouldn't work for us.
Being a host myself, if a guest told me on the day that they showed up that the place wouldn't work for them, I would immediately offer them a full refund with no questions asked. It's just good business practice and good guest service.
We were stuck for 30 days in a place that could not accommodate our needs.
Also, it is NOT within walking distance of Lisbon attractions. You'll need to take a 15 to 20 minute car ride to get to Lisbon city center.
Overall, it was very disappointing and I would not book with this host, or company, again.
