Apartment: 4/5 stars, really nice and good location, well equipped and quality comfortable furniture.
The downside was that there is major renovations going on in the apartment next door during the day, with a lot of hammering drilling etc. But obviously this is just a fact of life and Lisbon is developing fast so not much we can do about that. I guess it will be completed soon.
Checkin: 1/5 - somehow things got very confused and the checkin was delayed, with the host thinking that one of our party was actually another member of the host team, sending us a message saying "Dont tell the client, but the keys are in the main station, please go and pick it up", i.e. travel 20 mins from the apartment and 20 minutes back, when we were already waiting to checkin. Presumably the message was for someone else! Not sure how the confusion happened but in the end it was OK, after some delays and strange communication the checkin was completed. Some small issue checking out, as one of our party wanted to stay a bit longer but this wasnt possible, the host kindly let them keep their bags in the apartment however which was good.
Overall, I think the host checkin process was confused and strange and not a great start, building works were noisy, but the stay was what we wanted and the apartment was good.
