We stayed for just over 4 weeks with our 18mo old and had a lovely stay in the flat. They dealt with minor issues in a timely manner and were very polite in all communications. The flat is exactly like the photos (actually felt bigger IRL which was a plus). It had everything you could want for a long term stay. If you are travelling with an infant, there is a highchair that straps to a dining chair, but no cot (not a problem as we have our own but just FYI).
The only downside I would mention are the trains that intermittently nearby, and blow their horn quite loudly. It’s only a few a day but they do run at any hour so before we got used to it, we were woken up at the early hours for a few nights. It’s nothing awful but if you’re a very light sleeper you may struggle.
Thanks to Brandy and Chris for everything- we would definitely stay again if we’re ever in Austin and would recommend.
