We stayed in Joaquin's apartment 2 nights (it was originally booked for 3 nights but we had a nightmare trip so we couldn't make it the first night).
The apartment is basic but very clean and comfortable. It is also extremely well located. Right in the city centre close to all the main tourist attractions and bars, which is what brings the main downfall : NOISE
To be fair, Joaquín had already told us that there could be noise, but it's not really noise, it's like having the waiter from the bar underneath right in your bed with you. Unbearable .We had to sleep with ear plugs. This said the noise doesn't start until 8.30 so if you are planning on getting up early and going late to bed (after the bar closes) then it's fine. On the other hand, if you want to relax and stay in bed a little longer and make it a romantic and relaxed trip this is not the place for you.
