We enjoyed our time at Sebastian’s. It was well located and the communication was great.
The apt can definitely get chilly in winter, a nice touch would be a rug to break up all that cold tile floor. Make sure you bring slippers!
We had the lovely girl do laundry for us since the machines are not in the apt and are used by the staff (full each time we saw them). Unfortunately one of my shirts came back with bleach stains so keep in mind this is a possibility.
Overall we liked our stay and would recommend. As noted the stairs to the apartment are crazy, so not for elderly/unsteady walkers.
