Katherine is, by far, the best hostess I have ever encountered. She answered all questions before I got there and was very accommodating all along the way. I got in a little late and in her thoughtfulness brought coffee, cream, juice, bread, and jam so that I wasn't without a little something to wake up to in the morning.
The apartment is exactly as listed, although I feel the pictures do it little justice compared to what it actually is like. It is really a lovely apartment in a very nice and safe neighborhood. There are plenty of restaurants all around, as well as markets and easy access to the metro and buses.
The only "issue" I would mention has nothing to do with Katherine or the apartment, per se. The people upstairs are night owls and so if you are a light sleeper, bring ear plugs or they may wake you. Also, two buildings down from the apartment is a residential clinic where the residents are regularly in the back yard, chatting, playing games, barbecuing, etc., so I didn't find the balcony all that peaceful of a place on which to hang out. They are in no way overly loud or rambunctious, but there is constant chatter and activity, from the moment I woke up until I went to sleep, so I didn't much enjoy time on the balcony. If you don't mind the chatter, the balcony is lovely and the view of the wooded area and flowers are very lovely.
