I stayed at Hugo's for 2 weeks while doing a combination of exploring and working in Lisbon.
The apartment is situated in an absolutely stunning location next to the Barrio Alto, and the bars, restaurants and nightlife of Lisboa.
The Apartment itself was clean, nicely furnished, and well equipped. It has plenty of natural light with big windows and an open layout, with air conditioning that keeps the place cool during the heat of the day.
Hugo was very responsive and on-hand to offer advice on anything we needed. There are secondary amenities within easy reach of the apt (Pharmacies, Laundrettes, Supermarkets).
In short, thoroughly enjoyed my time there and would recommend.
