Vladimir is an extremely kind man, with a centrally located home. There's plenty of rooms in the apartment, I'd say that 5 fit very comfortably, 6 wouldn't be a problem. Everything is stocked for the most part, but I wish there was more lighting in the apartment. Just personal preference.
Note- you will have to uber everywhere, there's nothing walkable about this spot even though it looks like it's a 15-20 minute walk to Caesar's. The advantage of this, is that you never hit traffic if you're going to dinner or coming back from dinner off strip. This is a perfect unit to avoid the crowd and do everything you need to in Vegas.
