Four of us stayed for three nights in October 2019. This is a bright, airy and spacious flat in a very good location. The flat itself was a bit old, but all necessary furniture/appliances were well maintained. The kitchen was well equipped but we never got to use it actually.
It was also very easy to communicate with hosts - perhaps one of the best we've experienced on Airbnb. They offered a quick guidebook that is put together by their team, connected Airbnb messaging system with whatsapp which made communication much easier, and also had good tips about local areas/restaurants. We found the washing machine not working too well initially and got in touch with the host about it. Within an hour a handyman arrived and fixed it.
Check in time was later than usual (3pm) but we were allowed to leave our luggage earlier in the flat during the cleaning (12pm) which was very helpful. The host we met during check-in was very friendly, told us useful information and suggested nice restaurants (which were very good - thanks!). The hosts also helped keeping our luggage after we checked out, which was a huge help due to our late flight schedule.
I would stay here again next time I go to Lisbon.
