We had a very nice time in Maria's appartment! It was cozy, the location was great, right between Barrio and Alfama. Both in walking distance. Maria gave is very good tips! One minor thing is that the appartment didnt have aircon, so you had to open up the windows in the night, where the noise is coming from the streets. But that is to be expected in a beautifull lively city like Lisbon, so be sure to bring some earplugs with you if your a light sleeper ;)
