It never took Anna more than a 30 minutes to respond to any questions prior to booking and as we were planning the trip and arrival, she kindly sent us all the information we needed - incl how best to get to the flat etc.
Once at the flat, we were able to arrive a little early and Anna handed over a list and map and explained where we could be shopping, eating and having ice cream etc.
The flat is great, the rooms are big enough, each with plenty of storage, and all 3 rooms have air condition. The smaller (en-suite) bathroom is only suitable for one person at a time, but all in all thats fine. Kitchen had everything we needed and the living room was big enough to hang out in.
The location near the station means its not the quietest part of town and has people hanging out on the streets, but that was never an issue. The fact that travel was made very easy (airport transfer bus, metro and bus, HopOn HopOff stop all ca 5mins away) and that you could get to a few different supermarkets within 5-10mins made it very convenient.
