Property appearance looked just fine. Unfortunately the streets around the hotel have trash all along sidewalk. I know its not anything the hotel can do about that. In fact the property had excellent kind and helpful staff. My only complaint was last night there I had a group of people playing loud music and yelling as they toasted shots. I could hear through the walls this was an 18th birthday celebration. I asked front desk for music turned down but music continued til 3am. Final conclusion: Good place to stay Monday thru Friday morning but not weekends.

Expedia set this up for my soulmate and I after we found out the day before arriving- the hotel shut its doors. So- we would have been stranded. Alkram, the manager, of Extended stay in Alexandria Virginia made our visit a pleasant surprise. It was 10 minutes from my competition venue and walking distance from the grocery store and various restaurants! It was a better than expected visit. I would seriously consider visiting again.

It took 20 minutes for someone to come to the front desk to check-us in. He did not say a word and our keys did not even work.The hallways were littered with trash and there were other people with their hotel doors open, cooking food in the hallways, and going from room to room. It was very loud and the rooms were not sound proof at all.

Very thin walls, just walking down the hallway to our room, I could hear EVERYTHING in the other rooms from cooking, tvs, and sexual relations! Upon entering my room, the bathroom door was shut and opening it release an awful smell, so much so I check the toilet to see if the seal was bad allowing sewer gasses in. Very poor patch jobs on counter and walls, covered with caulk instead of paint, etc. Other patrons creeped me out so bad eyeing my 21 year old daughter I no longer felt safe enough to stay and was given a full refund for the 20 minutes I was there. As a female traveler, I just didn’t feel safe there.
