Natalia's flat was a good solution for us for our last two nights in BA. It is well located near to restaurants etc and also the metro.
The flat itself is pretty run down, from the photos it looks in tip top shape but infact quite a lot of minor things are broken or very shabby ie kitchen cupboard, chair in bedroom, table on balcony, walls that were once white, now scuffed and greying. we arrived to find two old pieces of toast in the toaster, an uncleared out (or cleaned out) fridge and old coffee clogging up the coffee machine. All this didn't bother us hugely but we did feel that when paying that much money a night a fully functioning and well cleaned flat can be expected.
