As a group of 5 widely-traveled couples who get a villa somewhere in Europe every year, we all bring our own benchmarks of a "great house." La Posada Romana hit every one of them. It is a fantastic home to enjoy as its own destination, or as a centrally-located home base for the major destinations of Andalucia.
To start, the owner, Miren, couldn't have been more helpful, particularly with a very thorough pre-trip packet, including helpful directions to the house with pictures of primary route landmarks. Also included are restaurant suggestions with pictures, contact numbers, websites, attractions, history, etc. -- essentially the House Book delivered to you before your arrival. Diego, the gardener, was always available with suggestions or to help with any requests.
The house itself is excellent for large groups. There is plenty of room for everyone to either gather together or find their own private space. While we didn't have any young children with us (ages ranged from mid-20s to early-60s), as parents we could appreciate that the house would be very well suited for all but the youngest (as there are many levels).
The kitchen is large and well stocked with equipment and serving ware. As seems to normally be the case, it proved to be the favored gathering spot and could accommodate the 10 of us easily. We also had everything we needed to make and enjoy large scale dinners.
The pool, sundeck and activities (ping pong, bocci) lent a relaxing resort-like component to the holiday.
You do need a vehicle unless you are particularly geared towards a 30 minute hike into town, up a fairly steep incline. It's a 4 minute drive otherwise. The track to the house is perhaps a bit daunting the first trip, but a non-event thereafter. However, the location couldn't be better -- the views can't be done justice in the pictures.
The house can get warm when closed up, but please note that this is coming from visitors from moderate/cool climates (NYC/SF/Toronto) and used to constant air conditioning. However, there is central A/C with a max low of 23C (74F). We visited in October during a perfectly mild and dry period -- 24/15 (75/58) and were perfectly comfortable when we opened the doors and windows (of which there are many large openings) to allow the breezes to come through, adding to the home's open and bright feeling.
We highly recommend Posada Romana, and thank Miren and Diego for a very memorable holiday!
