My husband and I and another couple spent 5 nights in Belle Epoque and had a wonderful time. The location is amazing - overlooking the beach and the promenade. We lucked out with the weather at the end of October and were able to take advantage of the lovely outdoor spaces as well/terrace.
Natalia and her team were very responsive to us as we communicated on our way in and had someone waiting when we arrived who showed us around. All the basic amenities are there for you - shampoo and liquid soap, hairdryers etc
The apartment was very clean and bright - really nice.
Another reviewer mentioned that it's difficult to use the car lift (basically an elevator for your car that takes you down several levels to the garage underground) to access the garage - it's definitely very tight getting in and out - but while the other person said to really not even try it - we had a 4 door "midsize" car and my husband managed it fine. It's not for a nervous driver though!
Also as others have mentioned - on Friday and Saturday nights you can hear people talking loudly and having fun right outside the place until the wee hours. It bothered me most on Friday as that was our first night in Spain and I wasn't sleeping well/hadn't adjusted to the time change - but on weekends you really might want to use earplugs if you're a light sleeper. This was not an issue other nights of the week at all.
We would definitely stay here again and recommend it to friends
