The flat was very spacious, with beautiful views, and really well located - right in the heart of the city and a walk away from all the main sights! Nelson was a good host - we really appreciated his fast responses and detailed messages before we arrived, which were very helpful. However, given that there was no heating, the flat got very cold. We used the little heaters in the bedroom at night, but during the day we were working remotely from the living room and they were not strong enough to heat the room which made it quite uncomfortable. I think the flat would be perfect for a summer holiday trip, but less convenient for a remote working week in the winter. The flat was not very bright either, which was also not ideal to work.
Having said that, we had a very enjoyable time in Lisbon!
