Ana and Luis are amazing. We stayed here for one month and the unit is very comfortable. Everything you could need for a long stay with a great location. Less than 10 minute walk to the centre of the old town. Ana and Luis will also make sure you know the best places to visit and eat with maps and directions to everything.
The only negative thing I can say about the place is the internet. On our 2nd day we lost wifi. Ana gave us another network to use, but this other network appears to be a public network to the entire building so be sure you are using a VPN and the speeds of this network are abysmal. The next day, the assigned network to the unit came back on and then proceeded to go off 5 to 6 times everyday for the rest of our stay. Unfortunately, we work online and make numerous VOIP calls everyday. This was not possible with this internet connection as calls and internet connection were dropped constantly. Streaming movies or TV shows is almost impossible.
If you're only doing some general web surfing or checking emails, this connection would be fine. If you work online or stream, the wifi is going to be an issue. To be fair to Ana and Luis, after the network went out the first time, we did not contact them to complain, we just figured that this was the state of the internet connection there.
