We stayed in Rick's place for 3 nights. We were a party of six and we didn't have any trouble sleeping since the flat is very spacious with four large bedrooms.
The flat is in a quiet area close to Koreatown with a metro station near by. As advertised, it is a recently renovated flat with brand new electric appliances and kitchen amenities.
The bathrooms were clean and there were fresh towels for all of us.
Rick was a great host, always quick to reply to our messages and phone calls and happy to take care any of our problems. When we first checked-in the floor was a bit dusty, but as soon as I mentioned it to Rick he offered to send in a cleaning crew. He also provided scales for us to weight our luggage when we were leaving from LA, on a very short notice and early in the morning.
The only minor problem was the noise from the flat on the first floor. We could hear them walking around and taking showers during the night, but apart from that they were not much of a bother.
I would recommend this place for large groups that look for a place to stay in LA.
