Manuel was a great host, welcoming and informative. The apartment is clean, and in excellent location in terms of having main attractions in walking distance. It is located in the heart of Bairo Alto, where fun takes place every night (in August at least). However if you intend to sleep in it may get noisy at times (with open windows). The upstairs sofa is also very comfortable for sleeping if preferred.
The flat overall was nice and comfortable, the only small disadvantage may be the small showers if you are a big person :)
