Lourenco was very responsive to all of our needs - we messaged over Whatsapp and it was instant communication. We could check out in the evening which was great because normally you are left lugging your suitcases around on the last day. The apartment was beautiful and clean and in a good location! Be prepared to walk up a big hill to get there (although you'll get used to it because Lisbon is very hilly!). The only thing I would say is that the heating in the apartment isn't the best (only two heaters) but I guess this doesn't matter in the summer months but I visited in February. This is only a small thing to note among loads of positives!
