Very clean and comfortable studios with kitchenette in a large apartment building, no traffic noise due to backyard orientation of most rooms. In summer (from October 31) there is a swimming pool on the rooftop. Also the service is perfect and available 24/7 for any problem you might have.
What does not work well, is the communication BEFORE arrival: We sent 3 messages via hotels.com, which the management did not receive. So you must wait until THEY contact you, which will be around 10 a.m. on the day of arrival, as the system cannot generate the 8 digit entrance code earlier. Depending on your neighbours, the beep-beep and other sounds may be disturbing for some people, as the long halls of the building are not carpeted. On arrival, you must present documents to security personnel (photos of which previously sent to the management), and you will be taken a photo and an index finger scan to open the barrier (seldom works, but as security is present 24/7, this in not really a problem).
If you want to have breakfast or a snack in your room, there are two supermarkets in Bolivar Street, just a few steps from the building, and a good bakery in Bolivar Street 176 open 6-21 hrs. Apart from the communication problems before arrival, we had a great stay and will certainly come back.
