Afonso's apartment is perfect if you don't want to get too tired walking up and down the beautiful (but steep) roads of Lisbon. It's located near the suggestive Tagus river, which you can admire from the windows. Moreover, there's everything you need within a few steps: public transport, the supermarket, cute shops, the wonderful Alfama neighborhood and several monuments/museums. The house has all the comforts you need whether you are coming for a weekend or for a longer stay: in particular, the kitchen is very well equipped so you can cook a nice meal at home. And you don't even need to wash the dishes, the dishwasher will do that for you.
In conclusion, we can't forget to mention that Afonso is always very kind and available, so we can do nothing but recommend his apartment to anyone wanting to explore this lovely city!
