We loved our stay at Julia's place and would actually rate this as a 4.5 if we could. There was tons of space for us to spread out, the views were spectacular and we had everything we needed. The stairs didn't bother us at all but could be a concern if you were someone who can't do a lot of them.
The things that we struggled with a bit were that we were not able to have a lot of appliances or things plugged in, without tripping the breaker. Julia was very responsive to this and reset it for us quickly, so all was well. The other thing was that we could hear people above us walking around and talking at times. This wasn't a huge problem either, just something of note. We really liked the decor and the beds were comfortable and there were some nice soaps and shampoos provided in the bathroom. We would stay here again!
