We liked the quaint condo feeling. The room had too much air freshener smell when arrived - had to leave the indies open for a long while . We were thankful you could open the windows

They are in the process of some renovations but no problem with noise or inconvenience. Staff was very nice and helpful. They do need to improve the breakfast which is very limited.
