Just back from a weekend in the apartment with my wife for 3 nights.
Apartment is very nice and has all the mod cons for a great weekend , location is excellent, right in the heart of the city with all the shops,bars etc
Hosts are very reponsive and helpfull
About 10 min walk to Alfama which is very nice and has the old town feel to it .
Overall a great place to stay , can be a bit noisy at night time due to its location but not a big issue for us .
