Do not expect anything big, but expect something cosy.
The room is narrow, but very comfy: it includes a private bathroom with a quite large shower, a sink and toilets; as well as a large and comfortable bed with plenty of pillows, TV, AC, and kind gifts for the guests :).
Lourdes has been very reactive when we contacted her the day of your arrival, and allowed us to leave our bags at her place a bit before check-in, even though the room was not ready yet.
The apartment is well located; close to public transports and the Gothic neighbourhood, yet in a calm street, far from the noisy ones full of tourists. You must walk a bit to reach the beaches, but they are not very far away either!
Keep in mind that the room does not offer much free space (e.g. for open suitcases), and that it does not include any kitchen (though there is a microwave, coffee, tea, etc, which are free to use in the common area). If this is not a requirement for you, then go for it: it has been a real pleasure to stay at Lourdes', and we would definitely stay there again in the future! Thanks again for you hospitality!
