The host was very kind and met us in the very late hours of like midnight to give us the keys and show us around the flat. She was very communicative and answered our questions quickly. The unit itself is in a central location and if you love a big market you are in the center of Rastro on Sundays!
We loved being able to walk to nearby stores, restaurants and having the metro close by! The unit is on the smaller side but I have nothing to compare to in Europe, maybe they are all that way. It has all the essentials you need except a drier which was a bit difficult since it rained several days and the outside hamper was not an option. We got a fresh set of towels and linens a few days into out stay which was nice :)
