This place is located in the heart of Alfama district, surrounded by many groceries, restaurant, etc. It is ~15 minutes from Santa Apolonia railway/subway station. Ana is a great host, very responsive and flexible.
The apartment is not that big, though is enough for a couple. It has all the amenities, including even a washing machine (haven't tried it actually). The only nuisance was a noise from the upstairs. Every morning at around 7 someone residing a floor above was walking back and forth and we heard every step. We even heard someone snoring at night. So, if you can tolerate with the noise, this place is a perfect match.
