Xavier is an amazing and super responsive host. The location is phenomenal too, in a beautiful neighborhood with great architecture and steps away from local eateries, the theatre, parks, and tons of attractions. It doesn't get roudy in the unit so you'll be well sheltered from noise outside, but it is very lively outside so enjoy it!
The building itself is naturally quite old and the drainage reflects that. With two people, you'll do well to keep your showers quick and space them out as the pipes don't drain as fast as they fill up.
