We stayed over the holiday & so spent real time in the flat (6 days). Overall: not a good value.
GOOD: Frank's communication is excellent-often responding within minutes. Security also great. Water pressure was good. High ceilings, great natural daylight, crown molding.
BAD: Kitchen: VERY dirty. Frank offered to have his cleaner come, but I didn't want the coordination hassle on Christmas Eve, so he refunded the cleaning fee. I scrubbed caked-on food off walls/appliances, wiped sticky shelves, etc. ICK. The whole place is a bit run down. Building is old and poorly maintained: a doorknob came off in hand, skirting boards fell off in the kitchen. Cut my foot on a poorly installed door jam. Smudgy handprints on doors, peeling paint. Some nice details shown in the pix are missing. I might have shrugged, except the place was so overpriced. On previous Christmases, I've stayed in nicer, cleaner flats within a 5-10 walk that were much less $. I thought this would a nice splurge, but no.
