We loved our stay at this apartment. It's super central (you can literally see the train station from the window) - close to everything. Communication with Tomas was great and he was quick, helpful and responsive despite multiple changes due to our flights being canceled and moved. The apartment was spotless and decoration is lovely. Bed was comfy too! Given that we were there for Sao Joao (massive party on the streets) and super central, I would say isolation is quite good. The only thing we missed was some storage space - there was only one little coat hanger so we couldn't really unpack.
