the positives:
This flat is excellently located. You can reach all the big sights, and fabulous tapas bars within minutes. The size of the flat is perfect for a weekend getaway where you plan to spend most of your time out and about. the balcony is a fabulous size, with a lovely backdrop, and the flat, in general, is finished to a good standard. shower was powerful and hot.
negatives: as is documented in other comments (reaching back quite a while) there is a bad smell in the bathroom area - a sewage type smell. As the bathroom is only split from the bedroom by a sliding door, you have to keep this closed in order to not stink out your bedroom space. we were not made aware of this by the hosts. it does not make for a nice smell in the morning. when we raised this with the Host during our stay, we were ignored. the smell is also evident in the buildings communal spaces. its manageable, however the blanking of travellers when this is raised is bad, and if it is irreparable, this should be reflected in the price of the apartment. there were other issues in the apartment - a loose stair rail, small amount of mould in the corner of the bathroom, and the sofa is pretty grubby. also, please add a tea towel in the kitchen, we were forced to use one of our bathroom towels. Also bedroom storage is sparse, so bear that in mind.
