I do not recommend this place. I stayed for over two months in late 2017 (Oct to Dec) and found it really unpleasant. The place was very dirty on my arrival; the bed, linen, crockery, kitchen utensils, etc. were old, or broken. The place hasn’t been renovated (esp the bathroom) at all, if ever. The apartment is way too expensive for the condition it is in. Also, it is rather dark and small, so a little claustrophobic. Over my time here, the wifi cut out, the building ran out of water, the wooden bed literally broke... This place isn’t well looked after, and it is NOT good value for money. I wouldn’t stay here again even if it was given to me for free.
The host is nice and friendly, but I would rather the place was spotless and in working order. Oscar was attentive, but given the really poor condition of the apartment I feel ripped off.
There are loads of much much better apartments in BA for the same price - in fact, this has been my worse experience to date, and I travel to BA every 12-18 months. If you can, stay elsewhere.
