We spent 2 nights in Hugo's studio apartment.
We were very pleased from our choice: excellent location due to its centrality (and yet very peaceful) and the apartment was welcoming, modern, very well organized, full of light and very comfortable.
We met Hugo at arrival. He was very professional and gave us pieces of advices that we treasured all along our staying in Porto.
We have no hesitation whatsoever at warmly advising toc toc studio! In fact, if we'll be back in Porto, we might well book it again.
