We had a lovely time in Lisbon and at Hugo's apartment. However the studio apartment has no windows or natural light. The room is at the top of four steeps sets of stairs and has no natural light or ventilation. Considering the heat and humidity of Lisbon at this time of the year (June) plus climbing the stairs each time, arriving into a hot apartment was not the most ideal. Hugo does provide two large fans which we used gratefully!
Of course we did book it without seeing any photos because it was being renovated.

Overall, the apartment is very modern and trendy and in a perfect location, right in the centre of the city. It's also very quiet and we never had any trouble sleeping. There is everything you need including a washing machine, coffee maker, plenty of storage and seating. A great apartment! But perhaps a window could be put in at some stage to make it even better!
