The location is central to the Tagus River and within walking distance to Lisbon's most famous neighborhoods. Nuno's apartment is a great place to stay. Everything is neat and very clean. It has all the comforts you want. The beds are also very comfortable. We also really liked that there are shutters for all the windows, cause we like to sleep in complete darkness.
Nuno is a real Superhost. Very communicative and very friendly. Very clear in explanations and nothing was too much. Nuno also gives good tips about the city or other things you ask about.
Conclusion: we highly recommend this apartment if you like to stay in Lisbon.
