We had such a great stay here! The studio is very spacious, the kitchen was super functional, and we had all needs met. Super clean which is a must for me... I'm a super picky traveler and was really pleased here. They are very upfront about the noise situation, which is very real. One would think... Oh how bad could it really be? But. It's loud. Felt like kids and the hallway traffic were IN our apartment with us. Lol But it would last only a couple hours at most. So, yes, thin walls and it gets pretty chilly at night. Also, the bathroom fan is a bit aggressive (loud!!) and doesn't have a separate switch from the light so you're stuck with it. Lol All things that aren't deal breakers for me considering how convenient, clean, spacious and comfortable the studio is, but worth explaining in case some are sensitive to noise. Overall I would be happy to stay at this studio again. Actually, ended up with a complimentary room at the luxury Morgan Group hotel, the Clift SF, for our last night in the city... and decided to stay put at the studio instead. :)
