We stayed at the the apartment managed by LovelyStay for two weeks in December 2022.
Pros:
Location: very central, few minutes from both Rossio Square and train station and Praça do Comércio.
The windows are soundproof and they are doing a really good job blocking the sound from an otherwise very busy neighbourhood.
Appliances were new and worked flawlessly. Having a Nespresso coffee machine in the kitchen and two dozen coffee pods was a nice touch!
Self check-in was easy and uneventful.
Communication with the LovelyStay team during our stay was easy and they responded to our inquiries right away.
Cons:
Spotty Wi-Fi network. The signal was strong only in the living room. One bedroom had virtually no signal.
Maintenance issues: dripping water in the toilets that was quite loud at night, and few flickering lights. The host tried to address these issues during our stay, however they reoccured. The dripping water issue was in particular annoying!
