The place is small but enough for one person. I guess it would be too tight for two.
I changed the hour of arrival and that was not a problem at all. Besides that they helped me to take my luggage upstairs.
Two small details: 1) I asked for directions three times as subway doesn’t show in google maps and I didn’t get any reply... so be ready to check out the subway map in internet.
2) Mind about the cleaning: there’s no device for that and depends on the previous guest. I was quite lucky even though I found a dirty things (but I am always for sparkling clean).
