My husband and I spent a month at Gonçalo's place. We went through dozens of apartments before making a choice, and we didn't regret it a bit.
We are software engineers working remotely, so we needed a laptop friendly space with internet connection good enough to keep our workplace up and running, and we had no problems with that .
The place itself was sparkling clean, really cozy, with very comfortable bed. There was a certain amount of noise - not from outside, from upstairs neighbours mostly, but it's clearly stated in the descpription, so we were prepared and not irritated. I had earplugs with me, but only needed them once.
Almost all of our questions were answered before we asked them and Gonçalo was always available for us. Everything was fine mostly, and when a couple of minor incidents happened, they were resolved in no time.
The end of our stay was darkened with growing COVID-19 outbreak, but Gonçalo showed us outstanding support, helping with all necessary information and even making calls on our behalf. When we had to stay a bit longer because of closed borders, Gonçalo arranged an alternative accomodation for us and offered a lot of encouragement, which we really needed - being frightened by unclear situation. We really appreciate it and feel lucky having Gonçalo as our host.
