Carlos was a great host and very nice with the check-in and throughout my stay. He also had some nice suggestions and tips on how best to enjoy Lisbon during the pandemic (regulations, opening times, etc).
The apartment itself is in a great location just off the Avendida da Liberdade, lots of bars and restaurants and a 15-20 minute walk to both Praca do Commercio and Principe Real.
The bedrooms were a bit smaller and tighter than I expected but the bedding was clean and comfortable. The kitchen and living area could have been far cleaner, the kitchen in particular was a bit sticky and a lot of the cutlery, plates and glasses clearly hadn't been properly washed.
The living room was also a bit dusty and dark because of the location of the windows. Some better and stronger lighting throughout would have been very helpful.
Overall a decent well-priced apartment very well located to explore Lisbon.
